Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610652, here are decompositions:

11 + 31610641 = 31610652
13 + 31610639 = 31610652
23 + 31610629 = 31610652
71 + 31610581 = 31610652
79 + 31610573 = 31610652
83 + 31610569 = 31610652
89 + 31610563 = 31610652
113 + 31610539 = 31610652

Showing the first eight; more decompositions exist.
