Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604882, here are decompositions:

19 + 31604863 = 31604882
79 + 31604803 = 31604882
139 + 31604743 = 31604882
151 + 31604731 = 31604882
163 + 31604719 = 31604882
193 + 31604689 = 31604882
241 + 31604641 = 31604882
271 + 31604611 = 31604882

Showing the first eight; more decompositions exist.
