Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444708, here are decompositions:

17 + 31444691 = 31444708
47 + 31444661 = 31444708
59 + 31444649 = 31444708
149 + 31444559 = 31444708
167 + 31444541 = 31444708
461 + 31444247 = 31444708
467 + 31444241 = 31444708
587 + 31444121 = 31444708

Showing the first eight; more decompositions exist.
