Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602564, here are decompositions:

43 + 31602521 = 31602564
47 + 31602517 = 31602564
67 + 31602497 = 31602564
83 + 31602481 = 31602564
107 + 31602457 = 31602564
113 + 31602451 = 31602564
163 + 31602401 = 31602564
167 + 31602397 = 31602564

Showing the first eight; more decompositions exist.
