Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596926, here are decompositions:

3 + 31596923 = 31596926
13 + 31596913 = 31596926
19 + 31596907 = 31596926
37 + 31596889 = 31596926
43 + 31596883 = 31596926
79 + 31596847 = 31596926
157 + 31596769 = 31596926
313 + 31596613 = 31596926

Showing the first eight; more decompositions exist.
