Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604186, here are decompositions:

199 + 31603987 = 31604186
307 + 31603879 = 31604186
577 + 31603609 = 31604186
619 + 31603567 = 31604186
877 + 31603309 = 31604186
937 + 31603249 = 31604186
1039 + 31603147 = 31604186
1063 + 31603123 = 31604186

Showing the first eight; more decompositions exist.
