Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1102, here are decompositions:
- 5 + 1097 = 1102
- 11 + 1091 = 1102
- 41 + 1061 = 1102
- 53 + 1049 = 1102
- 71 + 1031 = 1102
- 83 + 1019 = 1102
- 89 + 1013 = 1102
- 131 + 971 = 1102
Showing the first eight; more decompositions exist.

The digit sequence 1102 first appears in π at position 12,720 of the decimal expansion (the 12,720ordinal-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.
