Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450046, here are decompositions:

3 + 31450043 = 31450046
13 + 31450033 = 31450046
79 + 31449967 = 31450046
109 + 31449937 = 31450046
193 + 31449853 = 31450046
223 + 31449823 = 31450046
307 + 31449739 = 31450046
349 + 31449697 = 31450046

Showing the first eight; more decompositions exist.
