Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572666, here are decompositions:

  • 7 + 572659 = 572666
  • 13 + 572653 = 572666
  • 37 + 572629 = 572666
  • 67 + 572599 = 572666
  • 79 + 572587 = 572666
  • 229 + 572437 = 572666
  • 337 + 572329 = 572666
  • 397 + 572269 = 572666

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 572,666 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 572666 first appears in π at position 229,723 of the decimal expansion (the 229,723ordinal-suffix:rd 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.
