Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137766, here are decompositions:

23 + 137743 = 137766
29 + 137737 = 137766
43 + 137723 = 137766
53 + 137713 = 137766
59 + 137707 = 137766
67 + 137699 = 137766
107 + 137659 = 137766
113 + 137653 = 137766

Showing the first eight; more decompositions exist.
