Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12402, here are decompositions:

  • 11 + 12391 = 12402
  • 23 + 12379 = 12402
  • 29 + 12373 = 12402
  • 59 + 12343 = 12402
  • 73 + 12329 = 12402
  • 79 + 12323 = 12402
  • 101 + 12301 = 12402
  • 113 + 12289 = 12402

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12402 first appears in π at position 290,024 of the decimal expansion (the 290,024ordinal-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.
