Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4066, here are decompositions:
- 17 + 4049 = 4066
- 47 + 4019 = 4066
- 53 + 4013 = 4066
- 59 + 4007 = 4066
- 137 + 3929 = 4066
- 149 + 3917 = 4066
- 233 + 3833 = 4066
- 263 + 3803 = 4066
Showing the first eight; more decompositions exist.

The digit sequence 4066 first appears in π at position 6,655 of the decimal expansion (the 6,655ordinal-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.
