Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604910, here are decompositions:

47 + 31604863 = 31604910
61 + 31604849 = 31604910
107 + 31604803 = 31604910
151 + 31604759 = 31604910
163 + 31604747 = 31604910
167 + 31604743 = 31604910
179 + 31604731 = 31604910
191 + 31604719 = 31604910

Showing the first eight; more decompositions exist.
