Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481836, here are decompositions:

23 + 481813 = 481836
29 + 481807 = 481836
67 + 481769 = 481836
83 + 481753 = 481836
137 + 481699 = 481836
139 + 481697 = 481836
163 + 481673 = 481836
197 + 481639 = 481836

Showing the first eight; more decompositions exist.
