Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542780, here are decompositions:

  • 19 + 542761 = 542780
  • 61 + 542719 = 542780
  • 67 + 542713 = 542780
  • 97 + 542683 = 542780
  • 181 + 542599 = 542780
  • 193 + 542587 = 542780
  • 223 + 542557 = 542780
  • 229 + 542551 = 542780

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 542,780 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 542780 first appears in π at position 101,358 of the decimal expansion (the 101,358ordinal-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.
