Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448584, here are decompositions:

3 + 31448581 = 31448584
5 + 31448579 = 31448584
137 + 31448447 = 31448584
263 + 31448321 = 31448584
281 + 31448303 = 31448584
383 + 31448201 = 31448584
443 + 31448141 = 31448584
617 + 31447967 = 31448584

Showing the first eight; more decompositions exist.
