Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523046, here are decompositions:

19 + 31523027 = 31523046
43 + 31523003 = 31523046
59 + 31522987 = 31523046
67 + 31522979 = 31523046
109 + 31522937 = 31523046
157 + 31522889 = 31523046
173 + 31522873 = 31523046
199 + 31522847 = 31523046

Showing the first eight; more decompositions exist.
