Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448656, here are decompositions:

17 + 31448639 = 31448656
53 + 31448603 = 31448656
137 + 31448519 = 31448656
149 + 31448507 = 31448656
233 + 31448423 = 31448656
347 + 31448309 = 31448656
353 + 31448303 = 31448656
359 + 31448297 = 31448656

Showing the first eight; more decompositions exist.
