Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662678, here are decompositions:

29 + 8662649 = 8662678
137 + 8662541 = 8662678
191 + 8662487 = 8662678
197 + 8662481 = 8662678
281 + 8662397 = 8662678
359 + 8662319 = 8662678
419 + 8662259 = 8662678
461 + 8662217 = 8662678

Showing the first eight; more decompositions exist.
