Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448566, here are decompositions:

47 + 31448519 = 31448566
59 + 31448507 = 31448566
197 + 31448369 = 31448566
257 + 31448309 = 31448566
263 + 31448303 = 31448566
269 + 31448297 = 31448566
509 + 31448057 = 31448566
599 + 31447967 = 31448566

Showing the first eight; more decompositions exist.
