Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718370, here are decompositions:

149 + 8718221 = 8718370
173 + 8718197 = 8718370
179 + 8718191 = 8718370
257 + 8718113 = 8718370
281 + 8718089 = 8718370
359 + 8718011 = 8718370
383 + 8717987 = 8718370
389 + 8717981 = 8718370

Showing the first eight; more decompositions exist.
