Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718390, here are decompositions:

13 + 8718377 = 8718390
41 + 8718349 = 8718390
47 + 8718343 = 8718390
89 + 8718301 = 8718390
113 + 8718277 = 8718390
139 + 8718251 = 8718390
173 + 8718217 = 8718390
193 + 8718197 = 8718390

Showing the first eight; more decompositions exist.
