Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465732, here are decompositions:

5 + 31465727 = 31465732
59 + 31465673 = 31465732
71 + 31465661 = 31465732
83 + 31465649 = 31465732
101 + 31465631 = 31465732
113 + 31465619 = 31465732
131 + 31465601 = 31465732
251 + 31465481 = 31465732

Showing the first eight; more decompositions exist.
