Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180672, here are decompositions:

5 + 180667 = 180672
43 + 180629 = 180672
103 + 180569 = 180672
109 + 180563 = 180672
131 + 180541 = 180672
139 + 180533 = 180672
181 + 180491 = 180672
199 + 180473 = 180672

Showing the first eight; more decompositions exist.
