Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147780, here are decompositions:

7 + 147773 = 147780
11 + 147769 = 147780
19 + 147761 = 147780
37 + 147743 = 147780
41 + 147739 = 147780
53 + 147727 = 147780
71 + 147709 = 147780
107 + 147673 = 147780

Showing the first eight; more decompositions exist.
