Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615904, here are decompositions:

13 + 8615891 = 8615904
23 + 8615881 = 8615904
71 + 8615833 = 8615904
113 + 8615791 = 8615904
137 + 8615767 = 8615904
181 + 8615723 = 8615904
197 + 8615707 = 8615904
211 + 8615693 = 8615904

Showing the first eight; more decompositions exist.
