Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521624, here are decompositions:

43 + 521581 = 521624
67 + 521557 = 521624
73 + 521551 = 521624
97 + 521527 = 521624
127 + 521497 = 521624
223 + 521401 = 521624
307 + 521317 = 521624
373 + 521251 = 521624

Showing the first eight; more decompositions exist.
