Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523314, here are decompositions:

5 + 31523309 = 31523314
47 + 31523267 = 31523314
71 + 31523243 = 31523314
83 + 31523231 = 31523314
107 + 31523207 = 31523314
113 + 31523201 = 31523314
233 + 31523081 = 31523314
293 + 31523021 = 31523314

Showing the first eight; more decompositions exist.
