Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180622, here are decompositions:

5 + 180617 = 180622
53 + 180569 = 180622
59 + 180563 = 180622
83 + 180539 = 180622
89 + 180533 = 180622
131 + 180491 = 180622
149 + 180473 = 180622
251 + 180371 = 180622

Showing the first eight; more decompositions exist.
