Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618864, here are decompositions:

3 + 8618861 = 8618864
13 + 8618851 = 8618864
31 + 8618833 = 8618864
127 + 8618737 = 8618864
181 + 8618683 = 8618864
271 + 8618593 = 8618864
283 + 8618581 = 8618864
307 + 8618557 = 8618864

Showing the first eight; more decompositions exist.
