Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602588, here are decompositions:

7 + 31602581 = 31602588
67 + 31602521 = 31602588
71 + 31602517 = 31602588
107 + 31602481 = 31602588
131 + 31602457 = 31602588
137 + 31602451 = 31602588
167 + 31602421 = 31602588
191 + 31602397 = 31602588

Showing the first eight; more decompositions exist.
