Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596432, here are decompositions:

13 + 31596419 = 31596432
19 + 31596413 = 31596432
29 + 31596403 = 31596432
31 + 31596401 = 31596432
41 + 31596391 = 31596432
53 + 31596379 = 31596432
139 + 31596293 = 31596432
223 + 31596209 = 31596432

Showing the first eight; more decompositions exist.
