Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629278, here are decompositions:

37 + 8629241 = 8629278
79 + 8629199 = 8629278
107 + 8629171 = 8629278
109 + 8629169 = 8629278
137 + 8629141 = 8629278
139 + 8629139 = 8629278
191 + 8629087 = 8629278
199 + 8629079 = 8629278

Showing the first eight; more decompositions exist.
