Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444726, here are decompositions:

3 + 31444723 = 31444726
83 + 31444643 = 31444726
167 + 31444559 = 31444726
179 + 31444547 = 31444726
347 + 31444379 = 31444726
359 + 31444367 = 31444726
479 + 31444247 = 31444726
569 + 31444157 = 31444726

Showing the first eight; more decompositions exist.
