Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499914, here are decompositions:

71 + 31499843 = 31499914
293 + 31499621 = 31499914
353 + 31499561 = 31499914
503 + 31499411 = 31499914
587 + 31499327 = 31499914
617 + 31499297 = 31499914
647 + 31499267 = 31499914
683 + 31499231 = 31499914

Showing the first eight; more decompositions exist.
