Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738216, here are decompositions:

7 + 8738209 = 8738216
127 + 8738089 = 8738216
163 + 8738053 = 8738216
283 + 8737933 = 8738216
349 + 8737867 = 8738216
367 + 8737849 = 8738216
373 + 8737843 = 8738216
433 + 8737783 = 8738216

Showing the first eight; more decompositions exist.
