Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538804, here are decompositions:

3 + 538801 = 538804
5 + 538799 = 538804
41 + 538763 = 538804
53 + 538751 = 538804
83 + 538721 = 538804
107 + 538697 = 538804
251 + 538553 = 538804
281 + 538523 = 538804

Showing the first eight; more decompositions exist.
