Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19270, here are decompositions:

  • 3 + 19267 = 19270
  • 11 + 19259 = 19270
  • 59 + 19211 = 19270
  • 89 + 19181 = 19270
  • 107 + 19163 = 19270
  • 113 + 19157 = 19270
  • 131 + 19139 = 19270
  • 149 + 19121 = 19270

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19270 first appears in π at position 7,116 of the decimal expansion (the 7,116ordinal-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.
