Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448564, here are decompositions:

13 + 31448551 = 31448564
31 + 31448533 = 31448564
151 + 31448413 = 31448564
241 + 31448323 = 31448564
271 + 31448293 = 31448564
283 + 31448281 = 31448564
331 + 31448233 = 31448564
373 + 31448191 = 31448564

Showing the first eight; more decompositions exist.
