Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502584, here are decompositions:

23 + 31502561 = 31502584
101 + 31502483 = 31502584
251 + 31502333 = 31502584
401 + 31502183 = 31502584
647 + 31501937 = 31502584
677 + 31501907 = 31502584
761 + 31501823 = 31502584
857 + 31501727 = 31502584

Showing the first eight; more decompositions exist.
