Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521652, here are decompositions:

11 + 521641 = 521652
71 + 521581 = 521652
101 + 521551 = 521652
113 + 521539 = 521652
149 + 521503 = 521652
181 + 521471 = 521652
223 + 521429 = 521652
251 + 521401 = 521652

Showing the first eight; more decompositions exist.
