Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738278, here are decompositions:

5 + 8738273 = 8738278
47 + 8738231 = 8738278
149 + 8738129 = 8738278
191 + 8738087 = 8738278
449 + 8737829 = 8738278
569 + 8737709 = 8738278
701 + 8737577 = 8738278
797 + 8737481 = 8738278

Showing the first eight; more decompositions exist.
