Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615754, here are decompositions:

13 + 31615741 = 31615754
43 + 31615711 = 31615754
103 + 31615651 = 31615754
151 + 31615603 = 31615754
211 + 31615543 = 31615754
271 + 31615483 = 31615754
277 + 31615477 = 31615754
283 + 31615471 = 31615754

Showing the first eight; more decompositions exist.
