Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610568, here are decompositions:

5 + 31610563 = 31610568
7 + 31610561 = 31610568
29 + 31610539 = 31610568
47 + 31610521 = 31610568
131 + 31610437 = 31610568
179 + 31610389 = 31610568
229 + 31610339 = 31610568
251 + 31610317 = 31610568

Showing the first eight; more decompositions exist.
