Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738078, here are decompositions:

7 + 8738071 = 8738078
31 + 8738047 = 8738078
67 + 8738011 = 8738078
157 + 8737921 = 8738078
211 + 8737867 = 8738078
229 + 8737849 = 8738078
277 + 8737801 = 8738078
337 + 8737741 = 8738078

Showing the first eight; more decompositions exist.
