Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518766, here are decompositions:

89 + 31518677 = 31518766
107 + 31518659 = 31518766
113 + 31518653 = 31518766
173 + 31518593 = 31518766
479 + 31518287 = 31518766
557 + 31518209 = 31518766
569 + 31518197 = 31518766
593 + 31518173 = 31518766

Showing the first eight; more decompositions exist.
