Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523702, here are decompositions:

43 + 31523659 = 31523702
103 + 31523599 = 31523702
163 + 31523539 = 31523702
181 + 31523521 = 31523702
229 + 31523473 = 31523702
241 + 31523461 = 31523702
283 + 31523419 = 31523702
373 + 31523329 = 31523702

Showing the first eight; more decompositions exist.
