Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672740, here are decompositions:

  • 17 + 8672723 = 8672740
  • 53 + 8672687 = 8672740
  • 101 + 8672639 = 8672740
  • 179 + 8672561 = 8672740
  • 227 + 8672513 = 8672740
  • 239 + 8672501 = 8672740
  • 257 + 8672483 = 8672740
  • 269 + 8672471 = 8672740

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,672,740 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8672740 first appears in π at position 548,172 of the decimal expansion (the 548,172ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
