Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718570, here are decompositions:

31 + 8718539 = 8718570
67 + 8718503 = 8718570
79 + 8718491 = 8718570
83 + 8718487 = 8718570
101 + 8718469 = 8718570
109 + 8718461 = 8718570
131 + 8718439 = 8718570
139 + 8718431 = 8718570

Showing the first eight; more decompositions exist.
