Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523612, here are decompositions:

13 + 31523599 = 31523612
73 + 31523539 = 31523612
139 + 31523473 = 31523612
151 + 31523461 = 31523612
193 + 31523419 = 31523612
283 + 31523329 = 31523612
499 + 31523113 = 31523612
661 + 31522951 = 31523612

Showing the first eight; more decompositions exist.
