Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500636, here are decompositions:

47 + 31500589 = 31500636
67 + 31500569 = 31500636
107 + 31500529 = 31500636
127 + 31500509 = 31500636
149 + 31500487 = 31500636
173 + 31500463 = 31500636
179 + 31500457 = 31500636
229 + 31500407 = 31500636

Showing the first eight; more decompositions exist.
