Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604898, here are decompositions:

109 + 31604789 = 31604898
131 + 31604767 = 31604898
139 + 31604759 = 31604898
151 + 31604747 = 31604898
167 + 31604731 = 31604898
179 + 31604719 = 31604898
211 + 31604687 = 31604898
251 + 31604647 = 31604898

Showing the first eight; more decompositions exist.
