Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602664, here are decompositions:

3 + 31602661 = 31602664
17 + 31602647 = 31602664
83 + 31602581 = 31602664
167 + 31602497 = 31602664
263 + 31602401 = 31602664
311 + 31602353 = 31602664
347 + 31602317 = 31602664
383 + 31602281 = 31602664

Showing the first eight; more decompositions exist.
