Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29428, here are decompositions:

  • 5 + 29423 = 29428
  • 17 + 29411 = 29428
  • 29 + 29399 = 29428
  • 41 + 29387 = 29428
  • 89 + 29339 = 29428
  • 101 + 29327 = 29428
  • 131 + 29297 = 29428
  • 197 + 29231 = 29428

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29428 first appears in π at position 11,133 of the decimal expansion (the 11,133ordinal-suffix:rd 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.
