Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604804, here are decompositions:

37 + 31604767 = 31604804
61 + 31604743 = 31604804
73 + 31604731 = 31604804
157 + 31604647 = 31604804
163 + 31604641 = 31604804
193 + 31604611 = 31604804
271 + 31604533 = 31604804
307 + 31604497 = 31604804

Showing the first eight; more decompositions exist.
