Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538742, here are decompositions:

  • 3 + 538739 = 538742
  • 19 + 538723 = 538742
  • 31 + 538711 = 538742
  • 163 + 538579 = 538742
  • 181 + 538561 = 538742
  • 223 + 538519 = 538742
  • 229 + 538513 = 538742
  • 271 + 538471 = 538742

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 538,742 and was likely granted around 1894.

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

Position in π

The digit sequence 538742 first appears in π at position 267,780 of the decimal expansion (the 267,780ordinal-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.
