Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602744, here are decompositions:

53 + 31602691 = 31602744
71 + 31602673 = 31602744
83 + 31602661 = 31602744
97 + 31602647 = 31602744
113 + 31602631 = 31602744
157 + 31602587 = 31602744
163 + 31602581 = 31602744
223 + 31602521 = 31602744

Showing the first eight; more decompositions exist.
