Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468722, here are decompositions:

23 + 31468699 = 31468722
149 + 31468573 = 31468722
151 + 31468571 = 31468722
163 + 31468559 = 31468722
179 + 31468543 = 31468722
193 + 31468529 = 31468722
199 + 31468523 = 31468722
211 + 31468511 = 31468722

Showing the first eight; more decompositions exist.
