Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578690, here are decompositions:

  • 3 + 578687 = 578690
  • 31 + 578659 = 578690
  • 43 + 578647 = 578690
  • 103 + 578587 = 578690
  • 109 + 578581 = 578690
  • 127 + 578563 = 578690
  • 157 + 578533 = 578690
  • 181 + 578509 = 578690

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 578,690 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 578690 first appears in π at position 9,571 of the decimal expansion (the 9,571ordinal-suffix:st 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.
