Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1150, here are decompositions:
- 41 + 1109 = 1150
- 47 + 1103 = 1150
- 53 + 1097 = 1150
- 59 + 1091 = 1150
- 89 + 1061 = 1150
- 101 + 1049 = 1150
- 131 + 1019 = 1150
- 137 + 1013 = 1150
Showing the first eight; more decompositions exist.

The digit sequence 1150 first appears in π at position 14,986 of the decimal expansion (the 14,986ordinal-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.
