Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66268, here are decompositions:
- 29 + 66239 = 66268
- 47 + 66221 = 66268
- 89 + 66179 = 66268
- 107 + 66161 = 66268
- 131 + 66137 = 66268
- 179 + 66089 = 66268
- 197 + 66071 = 66268
- 227 + 66041 = 66268
Showing the first eight; more decompositions exist.

The digit sequence 66268 first appears in π at position 248,634 of the decimal expansion (the 248,634ordinal-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.
