Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7528, here are decompositions:
- 5 + 7523 = 7528
- 11 + 7517 = 7528
- 29 + 7499 = 7528
- 41 + 7487 = 7528
- 47 + 7481 = 7528
- 71 + 7457 = 7528
- 179 + 7349 = 7528
- 197 + 7331 = 7528
Showing the first eight; more decompositions exist.

The digit sequence 7528 first appears in π at position 865 of the decimal expansion (the 865ordinal-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.
