Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593082, here are decompositions:

71 + 31593011 = 31593082
89 + 31592993 = 31593082
233 + 31592849 = 31593082
239 + 31592843 = 31593082
419 + 31592663 = 31593082
431 + 31592651 = 31593082
461 + 31592621 = 31593082
593 + 31592489 = 31593082

Showing the first eight; more decompositions exist.
