Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31766, here are decompositions:

37 + 31729 = 31766
43 + 31723 = 31766
67 + 31699 = 31766
79 + 31687 = 31766
103 + 31663 = 31766
109 + 31657 = 31766
139 + 31627 = 31766
193 + 31573 = 31766

Showing the first eight; more decompositions exist.
