Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602982, here are decompositions:

23 + 31602959 = 31602982
83 + 31602899 = 31602982
179 + 31602803 = 31602982
293 + 31602689 = 31602982
401 + 31602581 = 31602982
443 + 31602539 = 31602982
461 + 31602521 = 31602982
659 + 31602323 = 31602982

Showing the first eight; more decompositions exist.
