Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596450, here are decompositions:

13 + 31596437 = 31596450
31 + 31596419 = 31596450
37 + 31596413 = 31596450
47 + 31596403 = 31596450
59 + 31596391 = 31596450
71 + 31596379 = 31596450
139 + 31596311 = 31596450
157 + 31596293 = 31596450

Showing the first eight; more decompositions exist.
