Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37280, here are decompositions:

  • 3 + 37277 = 37280
  • 7 + 37273 = 37280
  • 37 + 37243 = 37280
  • 79 + 37201 = 37280
  • 109 + 37171 = 37280
  • 157 + 37123 = 37280
  • 163 + 37117 = 37280
  • 193 + 37087 = 37280

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 37280 first appears in π at position 194,870 of the decimal expansion (the 194,870ordinal-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.
