Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503720, here are decompositions:

  • 3 + 503717 = 503720
  • 13 + 503707 = 503720
  • 67 + 503653 = 503720
  • 73 + 503647 = 503720
  • 97 + 503623 = 503720
  • 109 + 503611 = 503720
  • 127 + 503593 = 503720
  • 157 + 503563 = 503720

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 503,720 and was likely granted around 1893.

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

Position in π

The digit sequence 503720 first appears in π at position 807,102 of the decimal expansion (the 807,102ordinal-suffix:nd 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.
