Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2268, here are decompositions:
- 17 + 2251 = 2268
- 29 + 2239 = 2268
- 31 + 2237 = 2268
- 47 + 2221 = 2268
- 61 + 2207 = 2268
- 89 + 2179 = 2268
- 107 + 2161 = 2268
- 127 + 2141 = 2268
Showing the first eight; more decompositions exist.

The digit sequence 2268 first appears in π at position 964 of the decimal expansion (the 964ordinal-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.
