Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619422, here are decompositions:

239 + 31619183 = 31619422
251 + 31619171 = 31619422
293 + 31619129 = 31619422
431 + 31618991 = 31619422
479 + 31618943 = 31619422
521 + 31618901 = 31619422
599 + 31618823 = 31619422
641 + 31618781 = 31619422

Showing the first eight; more decompositions exist.
