Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602678, here are decompositions:

5 + 31602673 = 31602678
17 + 31602661 = 31602678
31 + 31602647 = 31602678
47 + 31602631 = 31602678
89 + 31602589 = 31602678
97 + 31602581 = 31602678
139 + 31602539 = 31602678
157 + 31602521 = 31602678

Showing the first eight; more decompositions exist.
