Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1066, here are decompositions:
- 3 + 1063 = 1066
- 5 + 1061 = 1066
- 17 + 1049 = 1066
- 47 + 1019 = 1066
- 53 + 1013 = 1066
- 83 + 983 = 1066
- 89 + 977 = 1066
- 113 + 953 = 1066
Showing the first eight; more decompositions exist.

The digit sequence 1066 first appears in π at position 1,892 of the decimal expansion (the 1,892ordinal-suffix:nd 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.
