Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738226, here are decompositions:

17 + 8738209 = 8738226
97 + 8738129 = 8738226
103 + 8738123 = 8738226
137 + 8738089 = 8738226
139 + 8738087 = 8738226
173 + 8738053 = 8738226
179 + 8738047 = 8738226
193 + 8738033 = 8738226

Showing the first eight; more decompositions exist.
