Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738156, here are decompositions:

67 + 8738089 = 8738156
73 + 8738083 = 8738156
103 + 8738053 = 8738156
109 + 8738047 = 8738156
223 + 8737933 = 8738156
283 + 8737873 = 8738156
307 + 8737849 = 8738156
313 + 8737843 = 8738156

Showing the first eight; more decompositions exist.
