Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147786, here are decompositions:

7 + 147779 = 147786
13 + 147773 = 147786
17 + 147769 = 147786
43 + 147743 = 147786
47 + 147739 = 147786
59 + 147727 = 147786
83 + 147703 = 147786
97 + 147689 = 147786

Showing the first eight; more decompositions exist.
