Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462818, here are decompositions:

7 + 31462811 = 31462818
11 + 31462807 = 31462818
47 + 31462771 = 31462818
59 + 31462759 = 31462818
61 + 31462757 = 31462818
67 + 31462751 = 31462818
71 + 31462747 = 31462818
89 + 31462729 = 31462818

Showing the first eight; more decompositions exist.
