Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500082, here are decompositions:

59 + 31500023 = 31500082
149 + 31499933 = 31500082
239 + 31499843 = 31500082
461 + 31499621 = 31500082
521 + 31499561 = 31500082
683 + 31499399 = 31500082
773 + 31499309 = 31500082
1019 + 31499063 = 31500082

Showing the first eight; more decompositions exist.
