Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615874, here are decompositions:

41 + 8615833 = 8615874
83 + 8615791 = 8615874
103 + 8615771 = 8615874
107 + 8615767 = 8615874
151 + 8615723 = 8615874
167 + 8615707 = 8615874
181 + 8615693 = 8615874
251 + 8615623 = 8615874

Showing the first eight; more decompositions exist.
