Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673240, here are decompositions:

19 + 8673221 = 8673240
31 + 8673209 = 8673240
41 + 8673199 = 8673240
53 + 8673187 = 8673240
73 + 8673167 = 8673240
83 + 8673157 = 8673240
109 + 8673131 = 8673240
113 + 8673127 = 8673240

Showing the first eight; more decompositions exist.
