Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465800, here are decompositions:

11 + 31465789 = 31465800
19 + 31465781 = 31465800
43 + 31465757 = 31465800
53 + 31465747 = 31465800
59 + 31465741 = 31465800
73 + 31465727 = 31465800
89 + 31465711 = 31465800
103 + 31465697 = 31465800

Showing the first eight; more decompositions exist.
