Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728862, here are decompositions:

13 + 8728849 = 8728862
151 + 8728711 = 8728862
199 + 8728663 = 8728862
271 + 8728591 = 8728862
283 + 8728579 = 8728862
313 + 8728549 = 8728862
349 + 8728513 = 8728862
379 + 8728483 = 8728862

Showing the first eight; more decompositions exist.
