Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719402, here are decompositions:

11 + 8719391 = 8719402
23 + 8719379 = 8719402
53 + 8719349 = 8719402
101 + 8719301 = 8719402
113 + 8719289 = 8719402
149 + 8719253 = 8719402
179 + 8719223 = 8719402
191 + 8719211 = 8719402

Showing the first eight; more decompositions exist.
