Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719822, here are decompositions:

3 + 8719819 = 8719822
5 + 8719817 = 8719822
281 + 8719541 = 8719822
401 + 8719421 = 8719822
431 + 8719391 = 8719822
443 + 8719379 = 8719822
521 + 8719301 = 8719822
569 + 8719253 = 8719822

Showing the first eight; more decompositions exist.
