Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722782, here are decompositions:

43 + 8722739 = 8722782
71 + 8722711 = 8722782
109 + 8722673 = 8722782
139 + 8722643 = 8722782
151 + 8722631 = 8722782
179 + 8722603 = 8722782
241 + 8722541 = 8722782
283 + 8722499 = 8722782

Showing the first eight; more decompositions exist.
