Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25470, here are decompositions:

  • 7 + 25463 = 25470
  • 13 + 25457 = 25470
  • 17 + 25453 = 25470
  • 23 + 25447 = 25470
  • 31 + 25439 = 25470
  • 47 + 25423 = 25470
  • 59 + 25411 = 25470
  • 61 + 25409 = 25470

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 25470 first appears in π at position 13,003 of the decimal expansion (the 13,003ordinal-suffix:rd 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.
