Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756640, here are decompositions:

7 + 8756633 = 8756640
17 + 8756623 = 8756640
31 + 8756609 = 8756640
47 + 8756593 = 8756640
73 + 8756567 = 8756640
83 + 8756557 = 8756640
89 + 8756551 = 8756640
107 + 8756533 = 8756640

Showing the first eight; more decompositions exist.
