Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8506, here are decompositions:

  • 5 + 8501 = 8506
  • 59 + 8447 = 8506
  • 83 + 8423 = 8506
  • 137 + 8369 = 8506
  • 233 + 8273 = 8506
  • 263 + 8243 = 8506
  • 269 + 8237 = 8506
  • 359 + 8147 = 8506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8506 first appears in π at position 2,397 of the decimal expansion (the 2,397ordinal-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.
