Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522618, here are decompositions:

17 + 522601 = 522618
97 + 522521 = 522618
101 + 522517 = 522618
139 + 522479 = 522618
149 + 522469 = 522618
179 + 522439 = 522618
227 + 522391 = 522618
281 + 522337 = 522618

Showing the first eight; more decompositions exist.
