Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604698, here are decompositions:

11 + 31604687 = 31604698
17 + 31604681 = 31604698
71 + 31604627 = 31604698
89 + 31604609 = 31604698
137 + 31604561 = 31604698
197 + 31604501 = 31604698
311 + 31604387 = 31604698
401 + 31604297 = 31604698

Showing the first eight; more decompositions exist.
