Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448896, here are decompositions:

5 + 31448891 = 31448896
179 + 31448717 = 31448896
197 + 31448699 = 31448896
257 + 31448639 = 31448896
293 + 31448603 = 31448896
317 + 31448579 = 31448896
389 + 31448507 = 31448896
449 + 31448447 = 31448896

Showing the first eight; more decompositions exist.
