Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444834, here are decompositions:

107 + 31444727 = 31444834
173 + 31444661 = 31444834
191 + 31444643 = 31444834
293 + 31444541 = 31444834
431 + 31444403 = 31444834
467 + 31444367 = 31444834
521 + 31444313 = 31444834
587 + 31444247 = 31444834

Showing the first eight; more decompositions exist.
