Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501844, here are decompositions:

3 + 501841 = 501844
17 + 501827 = 501844
23 + 501821 = 501844
41 + 501803 = 501844
113 + 501731 = 501844
137 + 501707 = 501844
227 + 501617 = 501844
251 + 501593 = 501844

Showing the first eight; more decompositions exist.
