Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522630, here are decompositions:

7 + 522623 = 522630
29 + 522601 = 522630
61 + 522569 = 522630
89 + 522541 = 522630
107 + 522523 = 522630
109 + 522521 = 522630
113 + 522517 = 522630
151 + 522479 = 522630

Showing the first eight; more decompositions exist.
