Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1190, here are decompositions:
- 3 + 1187 = 1190
- 19 + 1171 = 1190
- 37 + 1153 = 1190
- 61 + 1129 = 1190
- 67 + 1123 = 1190
- 73 + 1117 = 1190
- 97 + 1093 = 1190
- 103 + 1087 = 1190
Showing the first eight; more decompositions exist.

The digit sequence 1190 first appears in π at position 5,967 of the decimal expansion (the 5,967ordinal-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.
