Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602648, here are decompositions:

17 + 31602631 = 31602648
59 + 31602589 = 31602648
61 + 31602587 = 31602648
67 + 31602581 = 31602648
109 + 31602539 = 31602648
127 + 31602521 = 31602648
131 + 31602517 = 31602648
151 + 31602497 = 31602648

Showing the first eight; more decompositions exist.
