Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720774, here are decompositions:

3 + 8720771 = 8720774
61 + 8720713 = 8720774
67 + 8720707 = 8720774
103 + 8720671 = 8720774
151 + 8720623 = 8720774
157 + 8720617 = 8720774
193 + 8720581 = 8720774
241 + 8720533 = 8720774

Showing the first eight; more decompositions exist.
