Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572642, here are decompositions:

  • 3 + 572639 = 572642
  • 13 + 572629 = 572642
  • 43 + 572599 = 572642
  • 61 + 572581 = 572642
  • 151 + 572491 = 572642
  • 163 + 572479 = 572642
  • 181 + 572461 = 572642
  • 193 + 572449 = 572642

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 572,642 and was likely granted around 1896.

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

Position in π

The digit sequence 572642 first appears in π at position 117,074 of the decimal expansion (the 117,074ordinal-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.
