Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672804, here are decompositions:

3 + 8672801 = 8672804
13 + 8672791 = 8672804
31 + 8672773 = 8672804
37 + 8672767 = 8672804
73 + 8672731 = 8672804
97 + 8672707 = 8672804
157 + 8672647 = 8672804
163 + 8672641 = 8672804

Showing the first eight; more decompositions exist.
