Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619446, here are decompositions:

59 + 31619387 = 31619446
179 + 31619267 = 31619446
233 + 31619213 = 31619446
239 + 31619207 = 31619446
263 + 31619183 = 31619446
269 + 31619177 = 31619446
317 + 31619129 = 31619446
503 + 31618943 = 31619446

Showing the first eight; more decompositions exist.
