Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521744, here are decompositions:

37 + 521707 = 521744
73 + 521671 = 521744
103 + 521641 = 521744
163 + 521581 = 521744
193 + 521551 = 521744
211 + 521533 = 521744
241 + 521503 = 521744
367 + 521377 = 521744

Showing the first eight; more decompositions exist.
