Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39770, here are decompositions:

  • 37 + 39733 = 39770
  • 43 + 39727 = 39770
  • 61 + 39709 = 39770
  • 67 + 39703 = 39770
  • 103 + 39667 = 39770
  • 139 + 39631 = 39770
  • 151 + 39619 = 39770
  • 163 + 39607 = 39770

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 39770 first appears in π at position 10,477 of the decimal expansion (the 10,477ordinal-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.
