Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580820, here are decompositions:

  • 7 + 580813 = 580820
  • 13 + 580807 = 580820
  • 61 + 580759 = 580820
  • 73 + 580747 = 580820
  • 103 + 580717 = 580820
  • 109 + 580711 = 580820
  • 127 + 580693 = 580820
  • 157 + 580663 = 580820

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 580,820 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 580820 first appears in π at position 92,448 of the decimal expansion (the 92,448ordinal-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.
