Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147642, here are decompositions:

  • 13 + 147629 = 147642
  • 29 + 147613 = 147642
  • 59 + 147583 = 147642
  • 71 + 147571 = 147642
  • 101 + 147541 = 147642
  • 139 + 147503 = 147642
  • 191 + 147451 = 147642
  • 193 + 147449 = 147642

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 147,642 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 147642 first appears in π at position 186,724 of the decimal expansion (the 186,724ordinal-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.
