Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180966, here are decompositions:

7 + 180959 = 180966
17 + 180949 = 180966
59 + 180907 = 180966
83 + 180883 = 180966
167 + 180799 = 180966
173 + 180793 = 180966
193 + 180773 = 180966
337 + 180629 = 180966

Showing the first eight; more decompositions exist.
