Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718742, here are decompositions:

5 + 8718737 = 8718742
239 + 8718503 = 8718742
251 + 8718491 = 8718742
281 + 8718461 = 8718742
311 + 8718431 = 8718742
491 + 8718251 = 8718742
521 + 8718221 = 8718742
653 + 8718089 = 8718742

Showing the first eight; more decompositions exist.
