Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521936, here are decompositions:

7 + 521929 = 521936
13 + 521923 = 521936
67 + 521869 = 521936
127 + 521809 = 521936
193 + 521743 = 521936
229 + 521707 = 521936
277 + 521659 = 521936
379 + 521557 = 521936

Showing the first eight; more decompositions exist.
