Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523034, here are decompositions:

7 + 31523027 = 31523034
13 + 31523021 = 31523034
31 + 31523003 = 31523034
47 + 31522987 = 31523034
73 + 31522961 = 31523034
83 + 31522951 = 31523034
97 + 31522937 = 31523034
211 + 31522823 = 31523034

Showing the first eight; more decompositions exist.
