Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147782, here are decompositions:

3 + 147779 = 147782
13 + 147769 = 147782
43 + 147739 = 147782
73 + 147709 = 147782
79 + 147703 = 147782
109 + 147673 = 147782
199 + 147583 = 147782
211 + 147571 = 147782

Showing the first eight; more decompositions exist.
