Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626774, here are decompositions:

7 + 31626767 = 31626774
83 + 31626691 = 31626774
107 + 31626667 = 31626774
167 + 31626607 = 31626774
211 + 31626563 = 31626774
227 + 31626547 = 31626774
241 + 31626533 = 31626774
281 + 31626493 = 31626774

Showing the first eight; more decompositions exist.
