Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19338, here are decompositions:

  • 5 + 19333 = 19338
  • 19 + 19319 = 19338
  • 29 + 19309 = 19338
  • 37 + 19301 = 19338
  • 71 + 19267 = 19338
  • 79 + 19259 = 19338
  • 89 + 19249 = 19338
  • 101 + 19237 = 19338

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19338 first appears in π at position 146,056 of the decimal expansion (the 146,056ordinal-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.
