Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90428, here are decompositions:
- 31 + 90397 = 90428
- 139 + 90289 = 90428
- 157 + 90271 = 90428
- 181 + 90247 = 90428
- 211 + 90217 = 90428
- 229 + 90199 = 90428
- 241 + 90187 = 90428
- 307 + 90121 = 90428
Showing the first eight; more decompositions exist.

The digit sequence 90428 first appears in π at position 908 of the decimal expansion (the 908ordinal-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.
