Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450732, here are decompositions:

11 + 31450721 = 31450732
113 + 31450619 = 31450732
149 + 31450583 = 31450732
191 + 31450541 = 31450732
281 + 31450451 = 31450732
311 + 31450421 = 31450732
419 + 31450313 = 31450732
461 + 31450271 = 31450732

Showing the first eight; more decompositions exist.
