Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147768, here are decompositions:

7 + 147761 = 147768
29 + 147739 = 147768
41 + 147727 = 147768
59 + 147709 = 147768
79 + 147689 = 147768
97 + 147671 = 147768
107 + 147661 = 147768
139 + 147629 = 147768

Showing the first eight; more decompositions exist.
