Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722880, here are decompositions:

3 + 8722877 = 8722880
277 + 8722603 = 8722880
409 + 8722471 = 8722880
421 + 8722459 = 8722880
433 + 8722447 = 8722880
457 + 8722423 = 8722880
487 + 8722393 = 8722880
541 + 8722339 = 8722880

Showing the first eight; more decompositions exist.
