Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719444, here are decompositions:

3 + 8719441 = 8719444
23 + 8719421 = 8719444
53 + 8719391 = 8719444
137 + 8719307 = 8719444
191 + 8719253 = 8719444
233 + 8719211 = 8719444
257 + 8719187 = 8719444
281 + 8719163 = 8719444

Showing the first eight; more decompositions exist.
