Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722718, here are decompositions:

7 + 8722711 = 8722718
97 + 8722621 = 8722718
241 + 8722477 = 8722718
271 + 8722447 = 8722718
379 + 8722339 = 8722718
421 + 8722297 = 8722718
547 + 8722171 = 8722718
601 + 8722117 = 8722718

Showing the first eight; more decompositions exist.
