Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490852, here are decompositions:

31 + 31490821 = 31490852
73 + 31490779 = 31490852
79 + 31490773 = 31490852
139 + 31490713 = 31490852
193 + 31490659 = 31490852
223 + 31490629 = 31490852
229 + 31490623 = 31490852
373 + 31490479 = 31490852

Showing the first eight; more decompositions exist.
