Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2308, here are decompositions:
- 11 + 2297 = 2308
- 41 + 2267 = 2308
- 71 + 2237 = 2308
- 101 + 2207 = 2308
- 167 + 2141 = 2308
- 179 + 2129 = 2308
- 197 + 2111 = 2308
- 227 + 2081 = 2308
Showing the first eight; more decompositions exist.

The digit sequence 2308 first appears in π at position 825 of the decimal expansion (the 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.
