Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51472, here are decompositions:

  • 11 + 51461 = 51472
  • 23 + 51449 = 51472
  • 41 + 51431 = 51472
  • 53 + 51419 = 51472
  • 59 + 51413 = 51472
  • 89 + 51383 = 51472
  • 131 + 51341 = 51472
  • 233 + 51239 = 51472

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51472 first appears in π at position 283,618 of the decimal expansion (the 283,618ordinal-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.
