Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179730, here are decompositions:

11 + 179719 = 179730
13 + 179717 = 179730
37 + 179693 = 179730
41 + 179689 = 179730
43 + 179687 = 179730
59 + 179671 = 179730
71 + 179659 = 179730
73 + 179657 = 179730

Showing the first eight; more decompositions exist.
