Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628904, here are decompositions:

5 + 8628899 = 8628904
47 + 8628857 = 8628904
113 + 8628791 = 8628904
131 + 8628773 = 8628904
227 + 8628677 = 8628904
257 + 8628647 = 8628904
281 + 8628623 = 8628904
353 + 8628551 = 8628904

Showing the first eight; more decompositions exist.
