Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521570, here are decompositions:

3 + 521567 = 521570
13 + 521557 = 521570
19 + 521551 = 521570
31 + 521539 = 521570
37 + 521533 = 521570
43 + 521527 = 521570
67 + 521503 = 521570
73 + 521497 = 521570

Showing the first eight; more decompositions exist.
