Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604772, here are decompositions:

5 + 31604767 = 31604772
13 + 31604759 = 31604772
29 + 31604743 = 31604772
41 + 31604731 = 31604772
53 + 31604719 = 31604772
83 + 31604689 = 31604772
131 + 31604641 = 31604772
163 + 31604609 = 31604772

Showing the first eight; more decompositions exist.
