Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596618, here are decompositions:

5 + 31596613 = 31596618
7 + 31596611 = 31596618
47 + 31596571 = 31596618
107 + 31596511 = 31596618
181 + 31596437 = 31596618
199 + 31596419 = 31596618
227 + 31596391 = 31596618
239 + 31596379 = 31596618

Showing the first eight; more decompositions exist.
