Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742022, here are decompositions:

11 + 8742011 = 8742022
71 + 8741951 = 8742022
89 + 8741933 = 8742022
269 + 8741753 = 8742022
281 + 8741741 = 8742022
383 + 8741639 = 8742022
563 + 8741459 = 8742022
659 + 8741363 = 8742022

Showing the first eight; more decompositions exist.
