Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1144, here are decompositions:
- 41 + 1103 = 1144
- 47 + 1097 = 1144
- 53 + 1091 = 1144
- 83 + 1061 = 1144
- 113 + 1031 = 1144
- 131 + 1013 = 1144
- 167 + 977 = 1144
- 173 + 971 = 1144
Showing the first eight; more decompositions exist.

The digit sequence 1144 first appears in π at position 6,325 of the decimal expansion (the 6,325ordinal-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.
