Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2544, here are decompositions:
- 5 + 2539 = 2544
- 13 + 2531 = 2544
- 23 + 2521 = 2544
- 41 + 2503 = 2544
- 67 + 2477 = 2544
- 71 + 2473 = 2544
- 97 + 2447 = 2544
- 103 + 2441 = 2544
Showing the first eight; more decompositions exist.

The digit sequence 2544 first appears in π at position 19,911 of the decimal expansion (the 19,911ordinal-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.
