Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455914, here are decompositions:

13 + 31455901 = 31455914
37 + 31455877 = 31455914
73 + 31455841 = 31455914
163 + 31455751 = 31455914
211 + 31455703 = 31455914
277 + 31455637 = 31455914
283 + 31455631 = 31455914
487 + 31455427 = 31455914

Showing the first eight; more decompositions exist.
