Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572872, here are decompositions:

  • 5 + 572867 = 572872
  • 29 + 572843 = 572872
  • 59 + 572813 = 572872
  • 71 + 572801 = 572872
  • 173 + 572699 = 572872
  • 233 + 572639 = 572872
  • 239 + 572633 = 572872
  • 263 + 572609 = 572872

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 572,872 and was likely granted around 1896.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 572872 first appears in π at position 501,611 of the decimal expansion (the 501,611ordinal-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.
