Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2016, here are decompositions:
- 5 + 2011 = 2016
- 13 + 2003 = 2016
- 17 + 1999 = 2016
- 19 + 1997 = 2016
- 23 + 1993 = 2016
- 29 + 1987 = 2016
- 37 + 1979 = 2016
- 43 + 1973 = 2016
Showing the first eight; more decompositions exist.

The digit sequence 2016 first appears in π at position 7,174 of the decimal expansion (the 7,174ordinal-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.
