Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493914, here are decompositions:

5 + 31493909 = 31493914
131 + 31493783 = 31493914
197 + 31493717 = 31493914
401 + 31493513 = 31493914
467 + 31493447 = 31493914
593 + 31493321 = 31493914
743 + 31493171 = 31493914
761 + 31493153 = 31493914

Showing the first eight; more decompositions exist.
