Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738512, here are decompositions:

5 + 8738507 = 8738512
113 + 8738399 = 8738512
149 + 8738363 = 8738512
173 + 8738339 = 8738512
179 + 8738333 = 8738512
239 + 8738273 = 8738512
281 + 8738231 = 8738512
311 + 8738201 = 8738512

Showing the first eight; more decompositions exist.
