Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619248, here are decompositions:

41 + 31619207 = 31619248
71 + 31619177 = 31619248
131 + 31619117 = 31619248
239 + 31619009 = 31619248
257 + 31618991 = 31619248
347 + 31618901 = 31619248
467 + 31618781 = 31619248
701 + 31618547 = 31619248

Showing the first eight; more decompositions exist.
