Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604856, here are decompositions:

7 + 31604849 = 31604856
53 + 31604803 = 31604856
67 + 31604789 = 31604856
89 + 31604767 = 31604856
97 + 31604759 = 31604856
109 + 31604747 = 31604856
113 + 31604743 = 31604856
137 + 31604719 = 31604856

Showing the first eight; more decompositions exist.
