Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615884, here are decompositions:

3 + 8615881 = 8615884
5 + 8615879 = 8615884
113 + 8615771 = 8615884
191 + 8615693 = 8615884
227 + 8615657 = 8615884
293 + 8615591 = 8615884
317 + 8615567 = 8615884
461 + 8615423 = 8615884

Showing the first eight; more decompositions exist.
