Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19956, here are decompositions:
- 7 + 19949 = 19956
- 19 + 19937 = 19956
- 29 + 19927 = 19956
- 37 + 19919 = 19956
- 43 + 19913 = 19956
- 67 + 19889 = 19956
- 89 + 19867 = 19956
- 103 + 19853 = 19956
Showing the first eight; more decompositions exist.

The digit sequence 19956 first appears in π at position 704 of the decimal expansion (the 704ordinal-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.
