Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511634, here are decompositions:

23 + 31511611 = 31511634
83 + 31511551 = 31511634
97 + 31511537 = 31511634
101 + 31511533 = 31511634
107 + 31511527 = 31511634
131 + 31511503 = 31511634
151 + 31511483 = 31511634
157 + 31511477 = 31511634

Showing the first eight; more decompositions exist.
