Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18528, here are decompositions:
- 5 + 18523 = 18528
- 7 + 18521 = 18528
- 11 + 18517 = 18528
- 47 + 18481 = 18528
- 67 + 18461 = 18528
- 71 + 18457 = 18528
- 89 + 18439 = 18528
- 101 + 18427 = 18528
Showing the first eight; more decompositions exist.

The digit sequence 18528 first appears in π at position 6,825 of the decimal expansion (the 6,825ordinal-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.
