Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719278, here are decompositions:

5 + 8719273 = 8719278
17 + 8719261 = 8719278
59 + 8719219 = 8719278
67 + 8719211 = 8719278
79 + 8719199 = 8719278
101 + 8719177 = 8719278
137 + 8719141 = 8719278
151 + 8719127 = 8719278

Showing the first eight; more decompositions exist.
