Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738238, here are decompositions:

7 + 8738231 = 8738238
11 + 8738227 = 8738238
29 + 8738209 = 8738238
37 + 8738201 = 8738238
109 + 8738129 = 8738238
137 + 8738101 = 8738238
149 + 8738089 = 8738238
151 + 8738087 = 8738238

Showing the first eight; more decompositions exist.
