Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722752, here are decompositions:

13 + 8722739 = 8722752
41 + 8722711 = 8722752
79 + 8722673 = 8722752
109 + 8722643 = 8722752
131 + 8722621 = 8722752
139 + 8722613 = 8722752
149 + 8722603 = 8722752
211 + 8722541 = 8722752

Showing the first eight; more decompositions exist.
