Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516854, here are decompositions:

13 + 31516841 = 31516854
43 + 31516811 = 31516854
67 + 31516787 = 31516854
73 + 31516781 = 31516854
97 + 31516757 = 31516854
101 + 31516753 = 31516854
151 + 31516703 = 31516854
157 + 31516697 = 31516854

Showing the first eight; more decompositions exist.
