Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444702, here are decompositions:

11 + 31444691 = 31444702
41 + 31444661 = 31444702
53 + 31444649 = 31444702
59 + 31444643 = 31444702
71 + 31444631 = 31444702
389 + 31444313 = 31444702
461 + 31444241 = 31444702
683 + 31444019 = 31444702

Showing the first eight; more decompositions exist.
