Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17884, here are decompositions:

  • 3 + 17881 = 17884
  • 47 + 17837 = 17884
  • 101 + 17783 = 17884
  • 137 + 17747 = 17884
  • 227 + 17657 = 17884
  • 257 + 17627 = 17884
  • 311 + 17573 = 17884
  • 401 + 17483 = 17884

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17884 first appears in π at position 90,169 of the decimal expansion (the 90,169ordinal-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.
