Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465854, here are decompositions:

5 + 31465849 = 31465854
23 + 31465831 = 31465854
53 + 31465801 = 31465854
73 + 31465781 = 31465854
97 + 31465757 = 31465854
107 + 31465747 = 31465854
113 + 31465741 = 31465854
127 + 31465727 = 31465854

Showing the first eight; more decompositions exist.
