Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521612, here are decompositions:

31 + 521581 = 521612
61 + 521551 = 521612
73 + 521539 = 521612
79 + 521533 = 521612
109 + 521503 = 521612
211 + 521401 = 521612
283 + 521329 = 521612
313 + 521299 = 521612

Showing the first eight; more decompositions exist.
