Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2654, here are decompositions:
- 7 + 2647 = 2654
- 37 + 2617 = 2654
- 61 + 2593 = 2654
- 97 + 2557 = 2654
- 103 + 2551 = 2654
- 151 + 2503 = 2654
- 181 + 2473 = 2654
- 271 + 2383 = 2654
Showing the first eight; more decompositions exist.

The digit sequence 2654 first appears in π at position 1,559 of the decimal expansion (the 1,559ordinal-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.
