Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523762, here are decompositions:

13 + 31523749 = 31523762
103 + 31523659 = 31523762
163 + 31523599 = 31523762
223 + 31523539 = 31523762
241 + 31523521 = 31523762
433 + 31523329 = 31523762
541 + 31523221 = 31523762
601 + 31523161 = 31523762

Showing the first eight; more decompositions exist.
