Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2554, here are decompositions:
- 3 + 2551 = 2554
- 5 + 2549 = 2554
- 11 + 2543 = 2554
- 23 + 2531 = 2554
- 107 + 2447 = 2554
- 113 + 2441 = 2554
- 131 + 2423 = 2554
- 137 + 2417 = 2554
Showing the first eight; more decompositions exist.

The digit sequence 2554 first appears in π at position 8,711 of the decimal expansion (the 8,711ordinal-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.
