Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1526, here are decompositions:
- 3 + 1523 = 1526
- 37 + 1489 = 1526
- 43 + 1483 = 1526
- 67 + 1459 = 1526
- 73 + 1453 = 1526
- 79 + 1447 = 1526
- 97 + 1429 = 1526
- 103 + 1423 = 1526
Showing the first eight; more decompositions exist.

The digit sequence 1526 first appears in π at position 17,039 of the decimal expansion (the 17,039ordinal-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.
