Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542690, here are decompositions:

  • 3 + 542687 = 542690
  • 7 + 542683 = 542690
  • 103 + 542587 = 542690
  • 139 + 542551 = 542690
  • 151 + 542539 = 542690
  • 157 + 542533 = 542690
  • 193 + 542497 = 542690
  • 223 + 542467 = 542690

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 542,690 and was likely granted around 1895.

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

Position in π

The digit sequence 542690 first appears in π at position 857,658 of the decimal expansion (the 857,658ordinal-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.
