Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500792, here are decompositions:

19 + 31500773 = 31500792
73 + 31500719 = 31500792
79 + 31500713 = 31500792
101 + 31500691 = 31500792
181 + 31500611 = 31500792
223 + 31500569 = 31500792
233 + 31500559 = 31500792
263 + 31500529 = 31500792

Showing the first eight; more decompositions exist.
