Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6812, here are decompositions:
- 19 + 6793 = 6812
- 31 + 6781 = 6812
- 79 + 6733 = 6812
- 103 + 6709 = 6812
- 109 + 6703 = 6812
- 139 + 6673 = 6812
- 151 + 6661 = 6812
- 193 + 6619 = 6812
Showing the first eight; more decompositions exist.

The digit sequence 6812 first appears in π at position 605 of the decimal expansion (the 605ordinal-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.
