Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602750, here are decompositions:

59 + 31602691 = 31602750
61 + 31602689 = 31602750
71 + 31602679 = 31602750
89 + 31602661 = 31602750
103 + 31602647 = 31602750
163 + 31602587 = 31602750
211 + 31602539 = 31602750
229 + 31602521 = 31602750

Showing the first eight; more decompositions exist.
