Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15562, here are decompositions:

  • 3 + 15559 = 15562
  • 11 + 15551 = 15562
  • 89 + 15473 = 15562
  • 101 + 15461 = 15562
  • 149 + 15413 = 15562
  • 179 + 15383 = 15562
  • 233 + 15329 = 15562
  • 263 + 15299 = 15562

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15562 first appears in π at position 70,127 of the decimal expansion (the 70,127ordinal-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.
