Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722826, here are decompositions:

37 + 8722789 = 8722826
223 + 8722603 = 8722826
349 + 8722477 = 8722826
367 + 8722459 = 8722826
379 + 8722447 = 8722826
397 + 8722429 = 8722826
433 + 8722393 = 8722826
487 + 8722339 = 8722826

Showing the first eight; more decompositions exist.
