Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758278, here are decompositions:

59 + 8758219 = 8758278
79 + 8758199 = 8758278
107 + 8758171 = 8758278
149 + 8758129 = 8758278
197 + 8758081 = 8758278
211 + 8758067 = 8758278
229 + 8758049 = 8758278
271 + 8758007 = 8758278

Showing the first eight; more decompositions exist.
