Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603956, here are decompositions:

23 + 31603933 = 31603956
37 + 31603919 = 31603956
67 + 31603889 = 31603956
79 + 31603877 = 31603956
113 + 31603843 = 31603956
127 + 31603829 = 31603956
199 + 31603757 = 31603956
239 + 31603717 = 31603956

Showing the first eight; more decompositions exist.
