Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38580, here are decompositions:

  • 11 + 38569 = 38580
  • 13 + 38567 = 38580
  • 19 + 38561 = 38580
  • 23 + 38557 = 38580
  • 37 + 38543 = 38580
  • 79 + 38501 = 38580
  • 127 + 38453 = 38580
  • 131 + 38449 = 38580

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 38580 first appears in π at position 32,590 of the decimal expansion (the 32,590ordinal-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.
