Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2196, here are decompositions:
- 17 + 2179 = 2196
- 43 + 2153 = 2196
- 53 + 2143 = 2196
- 59 + 2137 = 2196
- 67 + 2129 = 2196
- 83 + 2113 = 2196
- 97 + 2099 = 2196
- 107 + 2089 = 2196
Showing the first eight; more decompositions exist.

The digit sequence 2196 first appears in π at position 716 of the decimal expansion (the 716ordinal-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.
