Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469226, here are decompositions:

17 + 31469209 = 31469226
29 + 31469197 = 31469226
83 + 31469143 = 31469226
157 + 31469069 = 31469226
193 + 31469033 = 31469226
199 + 31469027 = 31469226
233 + 31468993 = 31469226
263 + 31468963 = 31469226

Showing the first eight; more decompositions exist.
