Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541956, here are decompositions:

23 + 31541933 = 31541956
53 + 31541903 = 31541956
263 + 31541693 = 31541956
359 + 31541597 = 31541956
449 + 31541507 = 31541956
557 + 31541399 = 31541956
659 + 31541297 = 31541956
827 + 31541129 = 31541956

Showing the first eight; more decompositions exist.
