Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148718, here are decompositions:

  • 7 + 148711 = 148718
  • 79 + 148639 = 148718
  • 109 + 148609 = 148718
  • 139 + 148579 = 148718
  • 181 + 148537 = 148718
  • 307 + 148411 = 148718
  • 331 + 148387 = 148718
  • 337 + 148381 = 148718

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 148,718 and was likely granted around 1873.

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

Position in π

The digit sequence 148718 first appears in π at position 641,282 of the decimal expansion (the 641,282ordinal-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.
