Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179790, here are decompositions:

11 + 179779 = 179790
41 + 179749 = 179790
47 + 179743 = 179790
53 + 179737 = 179790
71 + 179719 = 179790
73 + 179717 = 179790
97 + 179693 = 179790
101 + 179689 = 179790

Showing the first eight; more decompositions exist.
