Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718648, here are decompositions:

47 + 8718601 = 8718648
67 + 8718581 = 8718648
109 + 8718539 = 8718648
157 + 8718491 = 8718648
179 + 8718469 = 8718648
229 + 8718419 = 8718648
241 + 8718407 = 8718648
271 + 8718377 = 8718648

Showing the first eight; more decompositions exist.
