Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615916, here are decompositions:

37 + 8615879 = 8615916
83 + 8615833 = 8615916
107 + 8615809 = 8615916
149 + 8615767 = 8615916
167 + 8615749 = 8615916
193 + 8615723 = 8615916
223 + 8615693 = 8615916
263 + 8615653 = 8615916

Showing the first eight; more decompositions exist.
