Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718378, here are decompositions:

29 + 8718349 = 8718378
101 + 8718277 = 8718378
107 + 8718271 = 8718378
127 + 8718251 = 8718378
131 + 8718247 = 8718378
157 + 8718221 = 8718378
181 + 8718197 = 8718378
269 + 8718109 = 8718378

Showing the first eight; more decompositions exist.
