Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1956, here are decompositions:
- 5 + 1951 = 1956
- 7 + 1949 = 1956
- 23 + 1933 = 1956
- 43 + 1913 = 1956
- 67 + 1889 = 1956
- 79 + 1877 = 1956
- 83 + 1873 = 1956
- 89 + 1867 = 1956
Showing the first eight; more decompositions exist.

The digit sequence 1956 first appears in π at position 2,960 of the decimal expansion (the 2,960ordinal-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.
