Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736080, here are decompositions:

7 + 8736073 = 8736080
19 + 8736061 = 8736080
43 + 8736037 = 8736080
79 + 8736001 = 8736080
109 + 8735971 = 8736080
139 + 8735941 = 8736080
229 + 8735851 = 8736080
271 + 8735809 = 8736080

Showing the first eight; more decompositions exist.
