Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523366, here are decompositions:

19 + 31523347 = 31523366
37 + 31523329 = 31523366
73 + 31523293 = 31523366
139 + 31523227 = 31523366
157 + 31523209 = 31523366
223 + 31523143 = 31523366
313 + 31523053 = 31523366
379 + 31522987 = 31523366

Showing the first eight; more decompositions exist.
