Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596498, here are decompositions:

61 + 31596437 = 31596498
79 + 31596419 = 31596498
97 + 31596401 = 31596498
107 + 31596391 = 31596498
181 + 31596317 = 31596498
191 + 31596307 = 31596498
347 + 31596151 = 31596498
379 + 31596119 = 31596498

Showing the first eight; more decompositions exist.
