Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523708, here are decompositions:

61 + 31523647 = 31523708
109 + 31523599 = 31523708
241 + 31523467 = 31523708
379 + 31523329 = 31523708
457 + 31523251 = 31523708
487 + 31523221 = 31523708
499 + 31523209 = 31523708
547 + 31523161 = 31523708

Showing the first eight; more decompositions exist.
