Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618960, here are decompositions:

37 + 8618923 = 8618960
43 + 8618917 = 8618960
67 + 8618893 = 8618960
109 + 8618851 = 8618960
127 + 8618833 = 8618960
151 + 8618809 = 8618960
211 + 8618749 = 8618960
223 + 8618737 = 8618960

Showing the first eight; more decompositions exist.
