Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113642, here are decompositions:

  • 19 + 113623 = 113642
  • 103 + 113539 = 113642
  • 271 + 113371 = 113642
  • 283 + 113359 = 113642
  • 313 + 113329 = 113642
  • 409 + 113233 = 113642
  • 433 + 113209 = 113642
  • 499 + 113143 = 113642

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 113,642 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 113642 first appears in π at position 776,227 of the decimal expansion (the 776,227ordinal-suffix:th 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.
