Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3812, here are decompositions:
- 19 + 3793 = 3812
- 43 + 3769 = 3812
- 73 + 3739 = 3812
- 79 + 3733 = 3812
- 103 + 3709 = 3812
- 139 + 3673 = 3812
- 181 + 3631 = 3812
- 199 + 3613 = 3812
Showing the first eight; more decompositions exist.

The digit sequence 3812 first appears in π at position 5,038 of the decimal expansion (the 5,038ordinal-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.
