Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469214, here are decompositions:

5 + 31469209 = 31469214
17 + 31469197 = 31469214
37 + 31469177 = 31469214
71 + 31469143 = 31469214
83 + 31469131 = 31469214
113 + 31469101 = 31469214
173 + 31469041 = 31469214
181 + 31469033 = 31469214

Showing the first eight; more decompositions exist.
