Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8566, here are decompositions:
- 3 + 8563 = 8566
- 23 + 8543 = 8566
- 29 + 8537 = 8566
- 53 + 8513 = 8566
- 137 + 8429 = 8566
- 179 + 8387 = 8566
- 197 + 8369 = 8566
- 269 + 8297 = 8566
Showing the first eight; more decompositions exist.

The digit sequence 8566 first appears in π at position 255 of the decimal expansion (the 255ordinal-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.
