Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523426, here are decompositions:

7 + 31523419 = 31523426
19 + 31523407 = 31523426
79 + 31523347 = 31523426
97 + 31523329 = 31523426
199 + 31523227 = 31523426
283 + 31523143 = 31523426
307 + 31523119 = 31523426
313 + 31523113 = 31523426

Showing the first eight; more decompositions exist.
