Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506026, here are decompositions:

37 + 31505989 = 31506026
43 + 31505983 = 31506026
67 + 31505959 = 31506026
103 + 31505923 = 31506026
367 + 31505659 = 31506026
457 + 31505569 = 31506026
499 + 31505527 = 31506026
733 + 31505293 = 31506026

Showing the first eight; more decompositions exist.
