Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2548, here are decompositions:
- 5 + 2543 = 2548
- 17 + 2531 = 2548
- 71 + 2477 = 2548
- 89 + 2459 = 2548
- 101 + 2447 = 2548
- 107 + 2441 = 2548
- 131 + 2417 = 2548
- 137 + 2411 = 2548
Showing the first eight; more decompositions exist.

The digit sequence 2548 first appears in π at position 4,585 of the decimal expansion (the 4,585ordinal-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.
