Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143766, here are decompositions:

23 + 143743 = 143766
37 + 143729 = 143766
47 + 143719 = 143766
67 + 143699 = 143766
79 + 143687 = 143766
89 + 143677 = 143766
97 + 143669 = 143766
113 + 143653 = 143766

Showing the first eight; more decompositions exist.
