Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489716, here are decompositions:

7 + 31489709 = 31489716
43 + 31489673 = 31489716
53 + 31489663 = 31489716
103 + 31489613 = 31489716
197 + 31489519 = 31489716
227 + 31489489 = 31489716
283 + 31489433 = 31489716
317 + 31489399 = 31489716

Showing the first eight; more decompositions exist.
