Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615104, here are decompositions:

7 + 31615097 = 31615104
41 + 31615063 = 31615104
43 + 31615061 = 31615104
97 + 31615007 = 31615104
151 + 31614953 = 31615104
163 + 31614941 = 31615104
223 + 31614881 = 31615104
251 + 31614853 = 31615104

Showing the first eight; more decompositions exist.
