Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532766, here are decompositions:

17 + 31532749 = 31532766
29 + 31532737 = 31532766
73 + 31532693 = 31532766
79 + 31532687 = 31532766
107 + 31532659 = 31532766
113 + 31532653 = 31532766
127 + 31532639 = 31532766
173 + 31532593 = 31532766

Showing the first eight; more decompositions exist.
