Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559396, here are decompositions:

13 + 31559383 = 31559396
79 + 31559317 = 31559396
157 + 31559239 = 31559396
433 + 31558963 = 31559396
439 + 31558957 = 31559396
457 + 31558939 = 31559396
499 + 31558897 = 31559396
577 + 31558819 = 31559396

Showing the first eight; more decompositions exist.
