Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602682, here are decompositions:

3 + 31602679 = 31602682
101 + 31602581 = 31602682
239 + 31602443 = 31602682
281 + 31602401 = 31602682
359 + 31602323 = 31602682
401 + 31602281 = 31602682
431 + 31602251 = 31602682
443 + 31602239 = 31602682

Showing the first eight; more decompositions exist.
