Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602670, here are decompositions:

23 + 31602647 = 31602670
83 + 31602587 = 31602670
89 + 31602581 = 31602670
131 + 31602539 = 31602670
149 + 31602521 = 31602670
173 + 31602497 = 31602670
227 + 31602443 = 31602670
269 + 31602401 = 31602670

Showing the first eight; more decompositions exist.
