Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19498, here are decompositions:

  • 29 + 19469 = 19498
  • 41 + 19457 = 19498
  • 71 + 19427 = 19498
  • 107 + 19391 = 19498
  • 179 + 19319 = 19498
  • 197 + 19301 = 19498
  • 239 + 19259 = 19498
  • 317 + 19181 = 19498

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19498 first appears in π at position 13,152 of the decimal expansion (the 13,152ordinal-suffix:nd 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.
