Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3238, here are decompositions:
- 17 + 3221 = 3238
- 29 + 3209 = 3238
- 47 + 3191 = 3238
- 71 + 3167 = 3238
- 101 + 3137 = 3238
- 149 + 3089 = 3238
- 197 + 3041 = 3238
- 227 + 3011 = 3238
Showing the first eight; more decompositions exist.

The digit sequence 3238 first appears in π at position 15 of the decimal expansion (the 15ordinal-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.
