Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18346, here are decompositions:

  • 5 + 18341 = 18346
  • 17 + 18329 = 18346
  • 59 + 18287 = 18346
  • 89 + 18257 = 18346
  • 113 + 18233 = 18346
  • 197 + 18149 = 18346
  • 227 + 18119 = 18346
  • 257 + 18089 = 18346

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18346 first appears in π at position 16,946 of the decimal expansion (the 16,946ordinal-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.
