Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521622, here are decompositions:

19 + 521603 = 521622
41 + 521581 = 521622
71 + 521551 = 521622
83 + 521539 = 521622
89 + 521533 = 521622
103 + 521519 = 521622
131 + 521491 = 521622
139 + 521483 = 521622

Showing the first eight; more decompositions exist.
