Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609804, here are decompositions:

11 + 31609793 = 31609804
101 + 31609703 = 31609804
113 + 31609691 = 31609804
173 + 31609631 = 31609804
227 + 31609577 = 31609804
257 + 31609547 = 31609804
263 + 31609541 = 31609804
311 + 31609493 = 31609804

Showing the first eight; more decompositions exist.
