Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19342, here are decompositions:

  • 23 + 19319 = 19342
  • 41 + 19301 = 19342
  • 53 + 19289 = 19342
  • 83 + 19259 = 19342
  • 131 + 19211 = 19342
  • 179 + 19163 = 19342
  • 263 + 19079 = 19342
  • 269 + 19073 = 19342

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19342 first appears in π at position 149,066 of the decimal expansion (the 149,066ordinal-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.
