Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722886, here are decompositions:

97 + 8722789 = 8722886
283 + 8722603 = 8722886
409 + 8722477 = 8722886
439 + 8722447 = 8722886
457 + 8722429 = 8722886
463 + 8722423 = 8722886
547 + 8722339 = 8722886
769 + 8722117 = 8722886

Showing the first eight; more decompositions exist.
