Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003866, here are decompositions:

47 + 1003819 = 1003866
79 + 1003787 = 1003866
103 + 1003763 = 1003866
109 + 1003757 = 1003866
113 + 1003753 = 1003866
137 + 1003729 = 1003866
173 + 1003693 = 1003866
239 + 1003627 = 1003866

Showing the first eight; more decompositions exist.
