Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003816, here are decompositions:

29 + 1003787 = 1003816
53 + 1003763 = 1003816
59 + 1003757 = 1003816
83 + 1003733 = 1003816
137 + 1003679 = 1003816
197 + 1003619 = 1003816
227 + 1003589 = 1003816
347 + 1003469 = 1003816

Showing the first eight; more decompositions exist.
