Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615984, here are decompositions:

43 + 8615941 = 8615984
67 + 8615917 = 8615984
103 + 8615881 = 8615984
151 + 8615833 = 8615984
193 + 8615791 = 8615984
277 + 8615707 = 8615984
331 + 8615653 = 8615984
397 + 8615587 = 8615984

Showing the first eight; more decompositions exist.
