Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719438, here are decompositions:

17 + 8719421 = 8719438
47 + 8719391 = 8719438
59 + 8719379 = 8719438
71 + 8719367 = 8719438
89 + 8719349 = 8719438
131 + 8719307 = 8719438
137 + 8719301 = 8719438
149 + 8719289 = 8719438

Showing the first eight; more decompositions exist.
