Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444876, here are decompositions:

5 + 31444871 = 31444876
149 + 31444727 = 31444876
227 + 31444649 = 31444876
233 + 31444643 = 31444876
317 + 31444559 = 31444876
509 + 31444367 = 31444876
563 + 31444313 = 31444876
719 + 31444157 = 31444876

Showing the first eight; more decompositions exist.
