Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450462, here are decompositions:

11 + 31450451 = 31450462
41 + 31450421 = 31450462
53 + 31450409 = 31450462
149 + 31450313 = 31450462
191 + 31450271 = 31450462
359 + 31450103 = 31450462
401 + 31450061 = 31450462
419 + 31450043 = 31450462

Showing the first eight; more decompositions exist.
