Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2586, here are decompositions:
- 7 + 2579 = 2586
- 29 + 2557 = 2586
- 37 + 2549 = 2586
- 43 + 2543 = 2586
- 47 + 2539 = 2586
- 83 + 2503 = 2586
- 109 + 2477 = 2586
- 113 + 2473 = 2586
Showing the first eight; more decompositions exist.

The digit sequence 2586 first appears in π at position 3,347 of the decimal expansion (the 3,347ordinal-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.
