Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470150, here are decompositions:

7 + 31470143 = 31470150
53 + 31470097 = 31470150
83 + 31470067 = 31470150
113 + 31470037 = 31470150
137 + 31470013 = 31470150
163 + 31469987 = 31470150
197 + 31469953 = 31470150
227 + 31469923 = 31470150

Showing the first eight; more decompositions exist.
