Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450652, here are decompositions:

31 + 31450621 = 31450652
73 + 31450579 = 31450652
109 + 31450543 = 31450652
223 + 31450429 = 31450652
229 + 31450423 = 31450652
241 + 31450411 = 31450652
283 + 31450369 = 31450652
433 + 31450219 = 31450652

Showing the first eight; more decompositions exist.
