Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602652, here are decompositions:

5 + 31602647 = 31602652
71 + 31602581 = 31602652
113 + 31602539 = 31602652
131 + 31602521 = 31602652
251 + 31602401 = 31602652
401 + 31602251 = 31602652
479 + 31602173 = 31602652
509 + 31602143 = 31602652

Showing the first eight; more decompositions exist.
