Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1146, here are decompositions:
- 17 + 1129 = 1146
- 23 + 1123 = 1146
- 29 + 1117 = 1146
- 37 + 1109 = 1146
- 43 + 1103 = 1146
- 53 + 1093 = 1146
- 59 + 1087 = 1146
- 83 + 1063 = 1146
Showing the first eight; more decompositions exist.

The digit sequence 1146 first appears in π at position 4,678 of the decimal expansion (the 4,678ordinal-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.
