Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445026, here are decompositions:

17 + 31445009 = 31445026
89 + 31444937 = 31445026
149 + 31444877 = 31445026
383 + 31444643 = 31445026
467 + 31444559 = 31445026
479 + 31444547 = 31445026
647 + 31444379 = 31445026
659 + 31444367 = 31445026

Showing the first eight; more decompositions exist.
