Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18734, here are decompositions:

  • 3 + 18731 = 18734
  • 43 + 18691 = 18734
  • 73 + 18661 = 18734
  • 97 + 18637 = 18734
  • 151 + 18583 = 18734
  • 181 + 18553 = 18734
  • 193 + 18541 = 18734
  • 211 + 18523 = 18734

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18734 first appears in π at position 106,992 of the decimal expansion (the 106,992ordinal-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.
