Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738222, here are decompositions:

13 + 8738209 = 8738222
61 + 8738161 = 8738222
139 + 8738083 = 8738222
151 + 8738071 = 8738222
211 + 8738011 = 8738222
349 + 8737873 = 8738222
373 + 8737849 = 8738222
379 + 8737843 = 8738222

Showing the first eight; more decompositions exist.
