Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738388, here are decompositions:

5 + 8738383 = 8738388
11 + 8738377 = 8738388
37 + 8738351 = 8738388
89 + 8738299 = 8738388
107 + 8738281 = 8738388
149 + 8738239 = 8738388
157 + 8738231 = 8738388
179 + 8738209 = 8738388

Showing the first eight; more decompositions exist.
