Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648156, here are decompositions:

7 + 8648149 = 8648156
43 + 8648113 = 8648156
73 + 8648083 = 8648156
163 + 8647993 = 8648156
193 + 8647963 = 8648156
229 + 8647927 = 8648156
277 + 8647879 = 8648156
337 + 8647819 = 8648156

Showing the first eight; more decompositions exist.
