Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542656, here are decompositions:

  • 53 + 542603 = 542656
  • 89 + 542567 = 542656
  • 137 + 542519 = 542656
  • 167 + 542489 = 542656
  • 173 + 542483 = 542656
  • 419 + 542237 = 542656
  • 449 + 542207 = 542656
  • 467 + 542189 = 542656

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 542,656 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 542656 first appears in π at position 303,517 of the decimal expansion (the 303,517ordinal-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.
