Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2358, here are decompositions:
- 7 + 2351 = 2358
- 11 + 2347 = 2358
- 17 + 2341 = 2358
- 19 + 2339 = 2358
- 47 + 2311 = 2358
- 61 + 2297 = 2358
- 71 + 2287 = 2358
- 89 + 2269 = 2358
Showing the first eight; more decompositions exist.

The digit sequence 2358 first appears in π at position 4,318 of the decimal expansion (the 4,318ordinal-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.
