Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1184, here are decompositions:
- 3 + 1181 = 1184
- 13 + 1171 = 1184
- 31 + 1153 = 1184
- 61 + 1123 = 1184
- 67 + 1117 = 1184
- 97 + 1087 = 1184
- 151 + 1033 = 1184
- 163 + 1021 = 1184
Showing the first eight; more decompositions exist.

The digit sequence 1184 first appears in π at position 13,356 of the decimal expansion (the 13,356ordinal-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.
