Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596492, here are decompositions:

19 + 31596473 = 31596492
73 + 31596419 = 31596492
79 + 31596413 = 31596492
89 + 31596403 = 31596492
101 + 31596391 = 31596492
113 + 31596379 = 31596492
181 + 31596311 = 31596492
199 + 31596293 = 31596492

Showing the first eight; more decompositions exist.
