Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450764, here are decompositions:

41 + 31450723 = 31450764
43 + 31450721 = 31450764
97 + 31450667 = 31450764
151 + 31450613 = 31450764
181 + 31450583 = 31450764
223 + 31450541 = 31450764
277 + 31450487 = 31450764
281 + 31450483 = 31450764

Showing the first eight; more decompositions exist.
