Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469232, here are decompositions:

23 + 31469209 = 31469232
89 + 31469143 = 31469232
101 + 31469131 = 31469232
131 + 31469101 = 31469232
163 + 31469069 = 31469232
191 + 31469041 = 31469232
199 + 31469033 = 31469232
239 + 31468993 = 31469232

Showing the first eight; more decompositions exist.
