Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450066, here are decompositions:

5 + 31450061 = 31450066
23 + 31450043 = 31450066
419 + 31449647 = 31450066
509 + 31449557 = 31450066
587 + 31449479 = 31450066
617 + 31449449 = 31450066
743 + 31449323 = 31450066
887 + 31449179 = 31450066

Showing the first eight; more decompositions exist.
