Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521844, here are decompositions:

13 + 521831 = 521844
31 + 521813 = 521844
53 + 521791 = 521844
67 + 521777 = 521844
101 + 521743 = 521844
137 + 521707 = 521844
151 + 521693 = 521844
173 + 521671 = 521844

Showing the first eight; more decompositions exist.
