Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613666, here are decompositions:

37 + 31613629 = 31613666
43 + 31613623 = 31613666
127 + 31613539 = 31613666
229 + 31613437 = 31613666
283 + 31613383 = 31613666
439 + 31613227 = 31613666
523 + 31613143 = 31613666
547 + 31613119 = 31613666

Showing the first eight; more decompositions exist.
