Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18354, here are decompositions:

  • 13 + 18341 = 18354
  • 41 + 18313 = 18354
  • 43 + 18311 = 18354
  • 47 + 18307 = 18354
  • 53 + 18301 = 18354
  • 67 + 18287 = 18354
  • 97 + 18257 = 18354
  • 101 + 18253 = 18354

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18354 first appears in π at position 16,268 of the decimal expansion (the 16,268ordinal-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.
