Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672648, here are decompositions:

7 + 8672641 = 8672648
97 + 8672551 = 8672648
109 + 8672539 = 8672648
139 + 8672509 = 8672648
241 + 8672407 = 8672648
409 + 8672239 = 8672648
487 + 8672161 = 8672648
547 + 8672101 = 8672648

Showing the first eight; more decompositions exist.
