Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481634, here are decompositions:

11 + 31481623 = 31481634
13 + 31481621 = 31481634
43 + 31481591 = 31481634
103 + 31481531 = 31481634
113 + 31481521 = 31481634
127 + 31481507 = 31481634
137 + 31481497 = 31481634
157 + 31481477 = 31481634

Showing the first eight; more decompositions exist.
