Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722022, here are decompositions:

3 + 8722019 = 8722022
13 + 8722009 = 8722022
109 + 8721913 = 8722022
139 + 8721883 = 8722022
349 + 8721673 = 8722022
523 + 8721499 = 8722022
541 + 8721481 = 8722022
619 + 8721403 = 8722022

Showing the first eight; more decompositions exist.
