Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500046, here are decompositions:

23 + 31500023 = 31500046
29 + 31500017 = 31500046
107 + 31499939 = 31500046
113 + 31499933 = 31500046
509 + 31499537 = 31500046
587 + 31499459 = 31500046
647 + 31499399 = 31500046
659 + 31499387 = 31500046

Showing the first eight; more decompositions exist.
