Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619960, here are decompositions:

17 + 8619943 = 8619960
23 + 8619937 = 8619960
67 + 8619893 = 8619960
101 + 8619859 = 8619960
103 + 8619857 = 8619960
149 + 8619811 = 8619960
163 + 8619797 = 8619960
241 + 8619719 = 8619960

Showing the first eight; more decompositions exist.
