Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719518, here are decompositions:

97 + 8719421 = 8719518
127 + 8719391 = 8719518
139 + 8719379 = 8719518
151 + 8719367 = 8719518
191 + 8719327 = 8719518
211 + 8719307 = 8719518
229 + 8719289 = 8719518
257 + 8719261 = 8719518

Showing the first eight; more decompositions exist.
