Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469164, here are decompositions:

131 + 31469033 = 31469164
137 + 31469027 = 31469164
197 + 31468967 = 31469164
263 + 31468901 = 31469164
593 + 31468571 = 31469164
641 + 31468523 = 31469164
647 + 31468517 = 31469164
653 + 31468511 = 31469164

Showing the first eight; more decompositions exist.
