Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722844, here are decompositions:

3 + 8722841 = 8722844
223 + 8722621 = 8722844
241 + 8722603 = 8722844
367 + 8722477 = 8722844
373 + 8722471 = 8722844
397 + 8722447 = 8722844
421 + 8722423 = 8722844
541 + 8722303 = 8722844

Showing the first eight; more decompositions exist.
