Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500762, here are decompositions:

43 + 31500719 = 31500762
61 + 31500701 = 31500762
71 + 31500691 = 31500762
103 + 31500659 = 31500762
113 + 31500649 = 31500762
151 + 31500611 = 31500762
173 + 31500589 = 31500762
193 + 31500569 = 31500762

Showing the first eight; more decompositions exist.
