Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672828, here are decompositions:

7 + 8672821 = 8672828
37 + 8672791 = 8672828
61 + 8672767 = 8672828
97 + 8672731 = 8672828
181 + 8672647 = 8672828
277 + 8672551 = 8672828
421 + 8672407 = 8672828
727 + 8672101 = 8672828

Showing the first eight; more decompositions exist.
