Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465904, here are decompositions:

13 + 31465891 = 31465904
73 + 31465831 = 31465904
103 + 31465801 = 31465904
157 + 31465747 = 31465904
163 + 31465741 = 31465904
193 + 31465711 = 31465904
241 + 31465663 = 31465904
487 + 31465417 = 31465904

Showing the first eight; more decompositions exist.
