Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4686, here are decompositions:
- 7 + 4679 = 4686
- 13 + 4673 = 4686
- 23 + 4663 = 4686
- 29 + 4657 = 4686
- 37 + 4649 = 4686
- 43 + 4643 = 4686
- 47 + 4639 = 4686
- 83 + 4603 = 4686
Showing the first eight; more decompositions exist.

The digit sequence 4686 first appears in π at position 25,700 of the decimal expansion (the 25,700ordinal-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.
