Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87506, here are decompositions:

  • 73 + 87433 = 87506
  • 79 + 87427 = 87506
  • 103 + 87403 = 87506
  • 193 + 87313 = 87506
  • 229 + 87277 = 87506
  • 283 + 87223 = 87506
  • 373 + 87133 = 87506
  • 457 + 87049 = 87506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 87506 first appears in π at position 43,572 of the decimal expansion (the 43,572ordinal-suffix:nd 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.
