Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738244, here are decompositions:

5 + 8738239 = 8738244
13 + 8738231 = 8738244
17 + 8738227 = 8738244
43 + 8738201 = 8738244
83 + 8738161 = 8738244
157 + 8738087 = 8738244
173 + 8738071 = 8738244
191 + 8738053 = 8738244

Showing the first eight; more decompositions exist.
