Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672844, here are decompositions:

13 + 8672831 = 8672844
23 + 8672821 = 8672844
43 + 8672801 = 8672844
53 + 8672791 = 8672844
71 + 8672773 = 8672844
113 + 8672731 = 8672844
137 + 8672707 = 8672844
157 + 8672687 = 8672844

Showing the first eight; more decompositions exist.
