Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450150, here are decompositions:

47 + 31450103 = 31450150
89 + 31450061 = 31450150
107 + 31450043 = 31450150
227 + 31449923 = 31450150
359 + 31449791 = 31450150
383 + 31449767 = 31450150
449 + 31449701 = 31450150
461 + 31449689 = 31450150

Showing the first eight; more decompositions exist.
