Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615246, here are decompositions:

17 + 31615229 = 31615246
29 + 31615217 = 31615246
53 + 31615193 = 31615246
59 + 31615187 = 31615246
83 + 31615163 = 31615246
137 + 31615109 = 31615246
149 + 31615097 = 31615246
233 + 31615013 = 31615246

Showing the first eight; more decompositions exist.
