Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2562, here are decompositions:
- 5 + 2557 = 2562
- 11 + 2551 = 2562
- 13 + 2549 = 2562
- 19 + 2543 = 2562
- 23 + 2539 = 2562
- 31 + 2531 = 2562
- 41 + 2521 = 2562
- 59 + 2503 = 2562
Showing the first eight; more decompositions exist.

The digit sequence 2562 first appears in π at position 3,084 of the decimal expansion (the 3,084ordinal-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.
