Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615844, here are decompositions:

11 + 8615833 = 8615844
53 + 8615791 = 8615844
73 + 8615771 = 8615844
137 + 8615707 = 8615844
151 + 8615693 = 8615844
191 + 8615653 = 8615844
257 + 8615587 = 8615844
277 + 8615567 = 8615844

Showing the first eight; more decompositions exist.
