Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500752, here are decompositions:

61 + 31500691 = 31500752
103 + 31500649 = 31500752
163 + 31500589 = 31500752
193 + 31500559 = 31500752
223 + 31500529 = 31500752
373 + 31500379 = 31500752
853 + 31499899 = 31500752
859 + 31499893 = 31500752

Showing the first eight; more decompositions exist.
