Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719290, here are decompositions:

17 + 8719273 = 8719290
29 + 8719261 = 8719290
37 + 8719253 = 8719290
67 + 8719223 = 8719290
71 + 8719219 = 8719290
79 + 8719211 = 8719290
103 + 8719187 = 8719290
113 + 8719177 = 8719290

Showing the first eight; more decompositions exist.
