Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619514, here are decompositions:

5 + 31619509 = 31619514
13 + 31619501 = 31619514
107 + 31619407 = 31619514
127 + 31619387 = 31619514
233 + 31619281 = 31619514
257 + 31619257 = 31619514
307 + 31619207 = 31619514
331 + 31619183 = 31619514

Showing the first eight; more decompositions exist.
