Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1112, here are decompositions:
- 3 + 1109 = 1112
- 19 + 1093 = 1112
- 43 + 1069 = 1112
- 61 + 1051 = 1112
- 73 + 1039 = 1112
- 79 + 1033 = 1112
- 103 + 1009 = 1112
- 193 + 919 = 1112
Showing the first eight; more decompositions exist.

The digit sequence 1112 first appears in π at position 12,701 of the decimal expansion (the 12,701ordinal-suffix:st 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.
