Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722942, here are decompositions:

29 + 8722913 = 8722942
83 + 8722859 = 8722942
101 + 8722841 = 8722942
113 + 8722829 = 8722942
269 + 8722673 = 8722942
281 + 8722661 = 8722942
311 + 8722631 = 8722942
401 + 8722541 = 8722942

Showing the first eight; more decompositions exist.
