Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602690, here are decompositions:

11 + 31602679 = 31602690
17 + 31602673 = 31602690
29 + 31602661 = 31602690
43 + 31602647 = 31602690
59 + 31602631 = 31602690
101 + 31602589 = 31602690
103 + 31602587 = 31602690
109 + 31602581 = 31602690

Showing the first eight; more decompositions exist.
