Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1912, here are decompositions:
- 5 + 1907 = 1912
- 11 + 1901 = 1912
- 23 + 1889 = 1912
- 41 + 1871 = 1912
- 89 + 1823 = 1912
- 101 + 1811 = 1912
- 179 + 1733 = 1912
- 191 + 1721 = 1912
Showing the first eight; more decompositions exist.

The digit sequence 1912 first appears in π at position 12,613 of the decimal expansion (the 12,613ordinal-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.
