Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448366, here are decompositions:

43 + 31448323 = 31448366
67 + 31448299 = 31448366
73 + 31448293 = 31448366
349 + 31448017 = 31448366
379 + 31447987 = 31448366
409 + 31447957 = 31448366
463 + 31447903 = 31448366
709 + 31447657 = 31448366

Showing the first eight; more decompositions exist.
