Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722812, here are decompositions:

13 + 8722799 = 8722812
23 + 8722789 = 8722812
73 + 8722739 = 8722812
101 + 8722711 = 8722812
139 + 8722673 = 8722812
151 + 8722661 = 8722812
181 + 8722631 = 8722812
191 + 8722621 = 8722812

Showing the first eight; more decompositions exist.
