Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450854, here are decompositions:

7 + 31450847 = 31450854
11 + 31450843 = 31450854
13 + 31450841 = 31450854
31 + 31450823 = 31450854
53 + 31450801 = 31450854
67 + 31450787 = 31450854
73 + 31450781 = 31450854
131 + 31450723 = 31450854

Showing the first eight; more decompositions exist.
