Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619410, here are decompositions:

3 + 31619407 = 31619410
23 + 31619387 = 31619410
83 + 31619327 = 31619410
149 + 31619261 = 31619410
197 + 31619213 = 31619410
227 + 31619183 = 31619410
233 + 31619177 = 31619410
239 + 31619171 = 31619410

Showing the first eight; more decompositions exist.
