Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718588, here are decompositions:

7 + 8718581 = 8718588
17 + 8718571 = 8718588
97 + 8718491 = 8718588
101 + 8718487 = 8718588
127 + 8718461 = 8718588
149 + 8718439 = 8718588
157 + 8718431 = 8718588
181 + 8718407 = 8718588

Showing the first eight; more decompositions exist.
