Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602584, here are decompositions:

3 + 31602581 = 31602584
67 + 31602517 = 31602584
103 + 31602481 = 31602584
127 + 31602457 = 31602584
163 + 31602421 = 31602584
367 + 31602217 = 31602584
421 + 31602163 = 31602584
463 + 31602121 = 31602584

Showing the first eight; more decompositions exist.
