Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180562, here are decompositions:

23 + 180539 = 180562
29 + 180533 = 180562
59 + 180503 = 180562
71 + 180491 = 180562
89 + 180473 = 180562
149 + 180413 = 180562
191 + 180371 = 180562
251 + 180311 = 180562

Showing the first eight; more decompositions exist.
