Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25434, here are decompositions:

  • 11 + 25423 = 25434
  • 23 + 25411 = 25434
  • 43 + 25391 = 25434
  • 61 + 25373 = 25434
  • 67 + 25367 = 25434
  • 113 + 25321 = 25434
  • 127 + 25307 = 25434
  • 131 + 25303 = 25434

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 25434 first appears in π at position 141,280 of the decimal expansion (the 141,280ordinal-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.
