Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184780, here are decompositions:

3 + 184777 = 184780
47 + 184733 = 184780
53 + 184727 = 184780
59 + 184721 = 184780
131 + 184649 = 184780
149 + 184631 = 184780
173 + 184607 = 184780
227 + 184553 = 184780

Showing the first eight; more decompositions exist.
