Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2480, here are decompositions:

  • 3 + 2477 = 2480
  • 7 + 2473 = 2480
  • 13 + 2467 = 2480
  • 43 + 2437 = 2480
  • 97 + 2383 = 2480
  • 103 + 2377 = 2480
  • 109 + 2371 = 2480
  • 139 + 2341 = 2480

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 2480 first appears in π at position 10,849 of the decimal expansion (the 10,849ordinal-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.
