Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496682, here are decompositions:

5 + 31496677 = 31496682
11 + 31496671 = 31496682
13 + 31496669 = 31496682
71 + 31496611 = 31496682
83 + 31496599 = 31496682
89 + 31496593 = 31496682
109 + 31496573 = 31496682
131 + 31496551 = 31496682

Showing the first eight; more decompositions exist.
