Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654278, here are decompositions:

29 + 8654249 = 8654278
41 + 8654237 = 8654278
47 + 8654231 = 8654278
107 + 8654171 = 8654278
131 + 8654147 = 8654278
167 + 8654111 = 8654278
179 + 8654099 = 8654278
239 + 8654039 = 8654278

Showing the first eight; more decompositions exist.
