Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542500, here are decompositions:

  • 3 + 542497 = 542500
  • 11 + 542489 = 542500
  • 17 + 542483 = 542500
  • 53 + 542447 = 542500
  • 59 + 542441 = 542500
  • 239 + 542261 = 542500
  • 263 + 542237 = 542500
  • 281 + 542219 = 542500

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 542,500 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 542500 first appears in π at position 978,659 of the decimal expansion (the 978,659ordinal-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.
