Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180790, here are decompositions:

11 + 180779 = 180790
17 + 180773 = 180790
41 + 180749 = 180790
59 + 180731 = 180790
89 + 180701 = 180790
167 + 180623 = 180790
173 + 180617 = 180790
227 + 180563 = 180790

Showing the first eight; more decompositions exist.
