Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6866, here are decompositions:
- 3 + 6863 = 6866
- 37 + 6829 = 6866
- 43 + 6823 = 6866
- 73 + 6793 = 6866
- 103 + 6763 = 6866
- 157 + 6709 = 6866
- 163 + 6703 = 6866
- 193 + 6673 = 6866
Showing the first eight; more decompositions exist.

The digit sequence 6866 first appears in π at position 6,911 of the decimal expansion (the 6,911ordinal-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.
