Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598936, here are decompositions:

3 + 31598933 = 31598936
13 + 31598923 = 31598936
73 + 31598863 = 31598936
79 + 31598857 = 31598936
97 + 31598839 = 31598936
157 + 31598779 = 31598936
487 + 31598449 = 31598936
709 + 31598227 = 31598936

Showing the first eight; more decompositions exist.
