Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3186, here are decompositions:
- 5 + 3181 = 3186
- 17 + 3169 = 3186
- 19 + 3167 = 3186
- 23 + 3163 = 3186
- 67 + 3119 = 3186
- 97 + 3089 = 3186
- 103 + 3083 = 3186
- 107 + 3079 = 3186
Showing the first eight; more decompositions exist.

The digit sequence 3186 first appears in π at position 4,836 of the decimal expansion (the 4,836ordinal-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.
