Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1916, here are decompositions:
- 3 + 1913 = 1916
- 37 + 1879 = 1916
- 43 + 1873 = 1916
- 127 + 1789 = 1916
- 139 + 1777 = 1916
- 157 + 1759 = 1916
- 163 + 1753 = 1916
- 193 + 1723 = 1916
Showing the first eight; more decompositions exist.

The digit sequence 1916 first appears in π at position 18,787 of the decimal expansion (the 18,787ordinal-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.
