Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542868, here are decompositions:

  • 31 + 542837 = 542868
  • 37 + 542831 = 542868
  • 47 + 542821 = 542868
  • 71 + 542797 = 542868
  • 97 + 542771 = 542868
  • 107 + 542761 = 542868
  • 149 + 542719 = 542868
  • 181 + 542687 = 542868

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 542,868 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 542868 first appears in π at position 401,049 of the decimal expansion (the 401,049ordinal-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.
