Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180718, here are decompositions:

17 + 180701 = 180718
71 + 180647 = 180718
89 + 180629 = 180718
101 + 180617 = 180718
149 + 180569 = 180718
179 + 180539 = 180718
227 + 180491 = 180718
281 + 180437 = 180718

Showing the first eight; more decompositions exist.
