Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672646, here are decompositions:

5 + 8672641 = 8672646
7 + 8672639 = 8672646
83 + 8672563 = 8672646
107 + 8672539 = 8672646
127 + 8672519 = 8672646
137 + 8672509 = 8672646
163 + 8672483 = 8672646
223 + 8672423 = 8672646

Showing the first eight; more decompositions exist.
