Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650278, here are decompositions:

19 + 8650259 = 8650278
59 + 8650219 = 8650278
61 + 8650217 = 8650278
67 + 8650211 = 8650278
89 + 8650189 = 8650278
127 + 8650151 = 8650278
137 + 8650141 = 8650278
149 + 8650129 = 8650278

Showing the first eight; more decompositions exist.
