Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448222, here are decompositions:

31 + 31448191 = 31448222
61 + 31448161 = 31448222
73 + 31448149 = 31448222
151 + 31448071 = 31448222
199 + 31448023 = 31448222
271 + 31447951 = 31448222
409 + 31447813 = 31448222
439 + 31447783 = 31448222

Showing the first eight; more decompositions exist.
