Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18896, here are decompositions:

  • 37 + 18859 = 18896
  • 103 + 18793 = 18896
  • 109 + 18787 = 18896
  • 139 + 18757 = 18896
  • 313 + 18583 = 18896
  • 373 + 18523 = 18896
  • 379 + 18517 = 18896
  • 439 + 18457 = 18896

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18896 first appears in π at position 242,528 of the decimal expansion (the 242,528ordinal-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.
