Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468270, here are decompositions:

11 + 31468259 = 31468270
23 + 31468247 = 31468270
47 + 31468223 = 31468270
59 + 31468211 = 31468270
101 + 31468169 = 31468270
173 + 31468097 = 31468270
257 + 31468013 = 31468270
269 + 31468001 = 31468270

Showing the first eight; more decompositions exist.
