Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615114, here are decompositions:

5 + 31615109 = 31615114
17 + 31615097 = 31615114
53 + 31615061 = 31615114
101 + 31615013 = 31615114
107 + 31615007 = 31615114
173 + 31614941 = 31615114
233 + 31614881 = 31615114
263 + 31614851 = 31615114

Showing the first eight; more decompositions exist.
