Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720022, here are decompositions:

23 + 8719999 = 8720022
61 + 8719961 = 8720022
71 + 8719951 = 8720022
79 + 8719943 = 8720022
83 + 8719939 = 8720022
149 + 8719873 = 8720022
191 + 8719831 = 8720022
251 + 8719771 = 8720022

Showing the first eight; more decompositions exist.
