Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147720, here are decompositions:

11 + 147709 = 147720
17 + 147703 = 147720
31 + 147689 = 147720
47 + 147673 = 147720
59 + 147661 = 147720
73 + 147647 = 147720
103 + 147617 = 147720
107 + 147613 = 147720

Showing the first eight; more decompositions exist.
