Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500632, here are decompositions:

43 + 31500589 = 31500632
73 + 31500559 = 31500632
103 + 31500529 = 31500632
181 + 31500451 = 31500632
271 + 31500361 = 31500632
439 + 31500193 = 31500632
643 + 31499989 = 31500632
733 + 31499899 = 31500632

Showing the first eight; more decompositions exist.
