Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147738, here are decompositions:

11 + 147727 = 147738
29 + 147709 = 147738
67 + 147671 = 147738
109 + 147629 = 147738
131 + 147607 = 147738
167 + 147571 = 147738
181 + 147557 = 147738
191 + 147547 = 147738

Showing the first eight; more decompositions exist.
