Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13480, here are decompositions:

  • 3 + 13477 = 13480
  • 11 + 13469 = 13480
  • 17 + 13463 = 13480
  • 23 + 13457 = 13480
  • 29 + 13451 = 13480
  • 59 + 13421 = 13480
  • 83 + 13397 = 13480
  • 113 + 13367 = 13480

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13480 first appears in π at position 82,430 of the decimal expansion (the 82,430ordinal-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.
