Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448522, here are decompositions:

3 + 31448519 = 31448522
43 + 31448479 = 31448522
73 + 31448449 = 31448522
109 + 31448413 = 31448522
199 + 31448323 = 31448522
223 + 31448299 = 31448522
229 + 31448293 = 31448522
241 + 31448281 = 31448522

Showing the first eight; more decompositions exist.
