Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1064, here are decompositions:
- 3 + 1061 = 1064
- 13 + 1051 = 1064
- 31 + 1033 = 1064
- 43 + 1021 = 1064
- 67 + 997 = 1064
- 73 + 991 = 1064
- 97 + 967 = 1064
- 127 + 937 = 1064
Showing the first eight; more decompositions exist.

The digit sequence 1064 first appears in π at position 7,353 of the decimal expansion (the 7,353ordinal-suffix:rd 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.
