Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2526, here are decompositions:
- 5 + 2521 = 2526
- 23 + 2503 = 2526
- 53 + 2473 = 2526
- 59 + 2467 = 2526
- 67 + 2459 = 2526
- 79 + 2447 = 2526
- 89 + 2437 = 2526
- 103 + 2423 = 2526
Showing the first eight; more decompositions exist.

The digit sequence 2526 first appears in π at position 49,276 of the decimal expansion (the 49,276ordinal-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.
