Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945938, here are decompositions:

31 + 945907 = 945938
127 + 945811 = 945938
139 + 945799 = 945938
151 + 945787 = 945938
199 + 945739 = 945938
307 + 945631 = 945938
337 + 945601 = 945938
349 + 945589 = 945938

Showing the first eight; more decompositions exist.
