Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19562, here are decompositions:

  • 3 + 19559 = 19562
  • 19 + 19543 = 19562
  • 31 + 19531 = 19562
  • 61 + 19501 = 19562
  • 73 + 19489 = 19562
  • 79 + 19483 = 19562
  • 139 + 19423 = 19562
  • 181 + 19381 = 19562

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19562 first appears in π at position 98,615 of the decimal expansion (the 98,615ordinal-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.
