Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28202, here are decompositions:

  • 19 + 28183 = 28202
  • 79 + 28123 = 28202
  • 103 + 28099 = 28202
  • 151 + 28051 = 28202
  • 241 + 27961 = 28202
  • 283 + 27919 = 28202
  • 379 + 27823 = 28202
  • 409 + 27793 = 28202

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 28202 first appears in π at position 372,186 of the decimal expansion (the 372,186ordinal-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.
