Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722862, here are decompositions:

3 + 8722859 = 8722862
73 + 8722789 = 8722862
151 + 8722711 = 8722862
241 + 8722621 = 8722862
433 + 8722429 = 8722862
439 + 8722423 = 8722862
523 + 8722339 = 8722862
571 + 8722291 = 8722862

Showing the first eight; more decompositions exist.
