Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55506, here are decompositions:

  • 5 + 55501 = 55506
  • 19 + 55487 = 55506
  • 37 + 55469 = 55506
  • 67 + 55439 = 55506
  • 107 + 55399 = 55506
  • 163 + 55343 = 55506
  • 167 + 55339 = 55506
  • 173 + 55333 = 55506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55506 first appears in π at position 181,820 of the decimal expansion (the 181,820ordinal-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.
