Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51424, here are decompositions:

  • 3 + 51421 = 51424
  • 5 + 51419 = 51424
  • 11 + 51413 = 51424
  • 17 + 51407 = 51424
  • 41 + 51383 = 51424
  • 83 + 51341 = 51424
  • 137 + 51287 = 51424
  • 167 + 51257 = 51424

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51424 first appears in π at position 43,287 of the decimal expansion (the 43,287ordinal-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.
