Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30106, here are decompositions:

  • 3 + 30103 = 30106
  • 17 + 30089 = 30106
  • 47 + 30059 = 30106
  • 59 + 30047 = 30106
  • 179 + 29927 = 30106
  • 227 + 29879 = 30106
  • 233 + 29873 = 30106
  • 239 + 29867 = 30106

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 30106 first appears in π at position 19,610 of the decimal expansion (the 19,610ordinal-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.
