Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469274, here are decompositions:

97 + 31469177 = 31469274
131 + 31469143 = 31469274
173 + 31469101 = 31469274
233 + 31469041 = 31469274
241 + 31469033 = 31469274
281 + 31468993 = 31469274
307 + 31468967 = 31469274
311 + 31468963 = 31469274

Showing the first eight; more decompositions exist.
