Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523228, here are decompositions:

7 + 31523221 = 31523228
19 + 31523209 = 31523228
67 + 31523161 = 31523228
97 + 31523131 = 31523228
109 + 31523119 = 31523228
241 + 31522987 = 31523228
277 + 31522951 = 31523228
571 + 31522657 = 31523228

Showing the first eight; more decompositions exist.
