Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469268, here are decompositions:

29 + 31469239 = 31469268
59 + 31469209 = 31469268
71 + 31469197 = 31469268
137 + 31469131 = 31469268
167 + 31469101 = 31469268
199 + 31469069 = 31469268
227 + 31469041 = 31469268
241 + 31469027 = 31469268

Showing the first eight; more decompositions exist.
