Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498766, here are decompositions:

3 + 31498763 = 31498766
109 + 31498657 = 31498766
127 + 31498639 = 31498766
487 + 31498279 = 31498766
577 + 31498189 = 31498766
643 + 31498123 = 31498766
727 + 31498039 = 31498766
757 + 31498009 = 31498766

Showing the first eight; more decompositions exist.
