Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180712, here are decompositions:

11 + 180701 = 180712
83 + 180629 = 180712
89 + 180623 = 180712
149 + 180563 = 180712
173 + 180539 = 180712
179 + 180533 = 180712
239 + 180473 = 180712
293 + 180419 = 180712

Showing the first eight; more decompositions exist.
