Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450734, here are decompositions:

11 + 31450723 = 31450734
13 + 31450721 = 31450734
67 + 31450667 = 31450734
113 + 31450621 = 31450734
131 + 31450603 = 31450734
151 + 31450583 = 31450734
157 + 31450577 = 31450734
191 + 31450543 = 31450734

Showing the first eight; more decompositions exist.
