Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602760, here are decompositions:

71 + 31602689 = 31602760
113 + 31602647 = 31602760
173 + 31602587 = 31602760
179 + 31602581 = 31602760
239 + 31602521 = 31602760
263 + 31602497 = 31602760
317 + 31602443 = 31602760
359 + 31602401 = 31602760

Showing the first eight; more decompositions exist.
