Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719284, here are decompositions:

11 + 8719273 = 8719284
23 + 8719261 = 8719284
31 + 8719253 = 8719284
61 + 8719223 = 8719284
71 + 8719213 = 8719284
73 + 8719211 = 8719284
97 + 8719187 = 8719284
107 + 8719177 = 8719284

Showing the first eight; more decompositions exist.
