Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672778, here are decompositions:

5 + 8672773 = 8672778
11 + 8672767 = 8672778
47 + 8672731 = 8672778
71 + 8672707 = 8672778
131 + 8672647 = 8672778
137 + 8672641 = 8672778
139 + 8672639 = 8672778
157 + 8672621 = 8672778

Showing the first eight; more decompositions exist.
