Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987318, here are decompositions:

  • 5 + 987313 = 987318
  • 19 + 987299 = 987318
  • 67 + 987251 = 987318
  • 107 + 987211 = 987318
  • 109 + 987209 = 987318
  • 127 + 987191 = 987318
  • 191 + 987127 = 987318
  • 229 + 987089 = 987318

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 987,318 and was likely granted around 1911.

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

Position in π

The digit sequence 987318 first appears in π at position 539,692 of the decimal expansion (the 539,692ordinal-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.
