Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4086, here are decompositions:
- 7 + 4079 = 4086
- 13 + 4073 = 4086
- 29 + 4057 = 4086
- 37 + 4049 = 4086
- 59 + 4027 = 4086
- 67 + 4019 = 4086
- 73 + 4013 = 4086
- 79 + 4007 = 4086
Showing the first eight; more decompositions exist.

The digit sequence 4086 first appears in π at position 9,794 of the decimal expansion (the 9,794ordinal-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.
