Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25250, here are decompositions:

  • 3 + 25247 = 25250
  • 7 + 25243 = 25250
  • 13 + 25237 = 25250
  • 31 + 25219 = 25250
  • 61 + 25189 = 25250
  • 67 + 25183 = 25250
  • 79 + 25171 = 25250
  • 97 + 25153 = 25250

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 25250 first appears in π at position 42,706 of the decimal expansion (the 42,706ordinal-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.
