Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542886, here are decompositions:

  • 13 + 542873 = 542886
  • 89 + 542797 = 542886
  • 103 + 542783 = 542886
  • 139 + 542747 = 542886
  • 163 + 542723 = 542886
  • 167 + 542719 = 542886
  • 173 + 542713 = 542886
  • 193 + 542693 = 542886

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 542,886 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 542886 first appears in π at position 488,615 of the decimal expansion (the 488,615ordinal-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.
