Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738000, here are decompositions:

67 + 8737933 = 8738000
79 + 8737921 = 8738000
127 + 8737873 = 8738000
151 + 8737849 = 8738000
157 + 8737843 = 8738000
199 + 8737801 = 8738000
211 + 8737789 = 8738000
283 + 8737717 = 8738000

Showing the first eight; more decompositions exist.
