Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481652, here are decompositions:

29 + 31481623 = 31481652
31 + 31481621 = 31481652
43 + 31481609 = 31481652
61 + 31481591 = 31481652
109 + 31481543 = 31481652
131 + 31481521 = 31481652
173 + 31481479 = 31481652
179 + 31481473 = 31481652

Showing the first eight; more decompositions exist.
