Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460938, here are decompositions:

11 + 31460927 = 31460938
59 + 31460879 = 31460938
101 + 31460837 = 31460938
107 + 31460831 = 31460938
281 + 31460657 = 31460938
389 + 31460549 = 31460938
401 + 31460537 = 31460938
569 + 31460369 = 31460938

Showing the first eight; more decompositions exist.
