Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719240, here are decompositions:

17 + 8719223 = 8719240
29 + 8719211 = 8719240
41 + 8719199 = 8719240
53 + 8719187 = 8719240
107 + 8719133 = 8719240
113 + 8719127 = 8719240
191 + 8719049 = 8719240
353 + 8718887 = 8719240

Showing the first eight; more decompositions exist.
