Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720754, here are decompositions:

41 + 8720713 = 8720754
47 + 8720707 = 8720754
61 + 8720693 = 8720754
67 + 8720687 = 8720754
73 + 8720681 = 8720754
83 + 8720671 = 8720754
127 + 8720627 = 8720754
131 + 8720623 = 8720754

Showing the first eight; more decompositions exist.
