Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045824, here are decompositions:

5 + 1045819 = 1045824
23 + 1045801 = 1045824
61 + 1045763 = 1045824
97 + 1045727 = 1045824
173 + 1045651 = 1045824
181 + 1045643 = 1045824
191 + 1045633 = 1045824
251 + 1045573 = 1045824

Showing the first eight; more decompositions exist.
