Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672930, here are decompositions:

3 + 8672927 = 8672930
61 + 8672869 = 8672930
109 + 8672821 = 8672930
139 + 8672791 = 8672930
151 + 8672779 = 8672930
157 + 8672773 = 8672930
163 + 8672767 = 8672930
199 + 8672731 = 8672930

Showing the first eight; more decompositions exist.
