Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468222, here are decompositions:

11 + 31468211 = 31468222
53 + 31468169 = 31468222
239 + 31467983 = 31468222
311 + 31467911 = 31468222
503 + 31467719 = 31468222
683 + 31467539 = 31468222
719 + 31467503 = 31468222
911 + 31467311 = 31468222

Showing the first eight; more decompositions exist.
