Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108742, here are decompositions:

  • 3 + 108739 = 108742
  • 239 + 108503 = 108742
  • 281 + 108461 = 108742
  • 383 + 108359 = 108742
  • 449 + 108293 = 108742
  • 479 + 108263 = 108742
  • 509 + 108233 = 108742
  • 563 + 108179 = 108742

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 108,742 and was likely granted around 1871.

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

Position in π

The digit sequence 108742 first appears in π at position 426,493 of the decimal expansion (the 426,493ordinal-suffix:rd 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.
