Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523050, here are decompositions:

23 + 31523027 = 31523050
29 + 31523021 = 31523050
47 + 31523003 = 31523050
71 + 31522979 = 31523050
89 + 31522961 = 31523050
113 + 31522937 = 31523050
149 + 31522901 = 31523050
227 + 31522823 = 31523050

Showing the first eight; more decompositions exist.
