Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604016, here are decompositions:

29 + 31603987 = 31604016
83 + 31603933 = 31604016
97 + 31603919 = 31604016
127 + 31603889 = 31604016
137 + 31603879 = 31604016
139 + 31603877 = 31604016
173 + 31603843 = 31604016
277 + 31603739 = 31604016

Showing the first eight; more decompositions exist.
