Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448216, here are decompositions:

67 + 31448149 = 31448216
193 + 31448023 = 31448216
199 + 31448017 = 31448216
229 + 31447987 = 31448216
313 + 31447903 = 31448216
379 + 31447837 = 31448216
433 + 31447783 = 31448216
643 + 31447573 = 31448216

Showing the first eight; more decompositions exist.
