Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542788, here are decompositions:

  • 5 + 542783 = 542788
  • 17 + 542771 = 542788
  • 41 + 542747 = 542788
  • 101 + 542687 = 542788
  • 251 + 542537 = 542788
  • 269 + 542519 = 542788
  • 347 + 542441 = 542788
  • 569 + 542219 = 542788

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 542,788 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 542788 first appears in π at position 525,119 of the decimal expansion (the 525,119ordinal-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.
