Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2258, here are decompositions:
- 7 + 2251 = 2258
- 19 + 2239 = 2258
- 37 + 2221 = 2258
- 79 + 2179 = 2258
- 97 + 2161 = 2258
- 127 + 2131 = 2258
- 229 + 2029 = 2258
- 241 + 2017 = 2258
Showing the first eight; more decompositions exist.

The digit sequence 2258 first appears in π at position 2,377 of the decimal expansion (the 2,377ordinal-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.
