Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558976, here are decompositions:

3 + 31558973 = 31558976
13 + 31558963 = 31558976
19 + 31558957 = 31558976
37 + 31558939 = 31558976
79 + 31558897 = 31558976
157 + 31558819 = 31558976
283 + 31558693 = 31558976
313 + 31558663 = 31558976

Showing the first eight; more decompositions exist.
