Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180522, here are decompositions:

11 + 180511 = 180522
19 + 180503 = 180522
31 + 180491 = 180522
59 + 180463 = 180522
103 + 180419 = 180522
109 + 180413 = 180522
131 + 180391 = 180522
151 + 180371 = 180522

Showing the first eight; more decompositions exist.
