Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619434, here are decompositions:

47 + 31619387 = 31619434
107 + 31619327 = 31619434
167 + 31619267 = 31619434
173 + 31619261 = 31619434
227 + 31619207 = 31619434
251 + 31619183 = 31619434
257 + 31619177 = 31619434
263 + 31619171 = 31619434

Showing the first eight; more decompositions exist.
