Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29890, here are decompositions:

  • 11 + 29879 = 29890
  • 17 + 29873 = 29890
  • 23 + 29867 = 29890
  • 53 + 29837 = 29890
  • 71 + 29819 = 29890
  • 101 + 29789 = 29890
  • 131 + 29759 = 29890
  • 137 + 29753 = 29890

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 29890 first appears in π at position 298,910 of the decimal expansion (the 298,910ordinal-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.
