Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500596, here are decompositions:

7 + 31500589 = 31500596
37 + 31500559 = 31500596
67 + 31500529 = 31500596
109 + 31500487 = 31500596
139 + 31500457 = 31500596
229 + 31500367 = 31500596
409 + 31500187 = 31500596
607 + 31499989 = 31500596

Showing the first eight; more decompositions exist.
