Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739078, here are decompositions:

71 + 8739007 = 8739078
149 + 8738929 = 8739078
197 + 8738881 = 8739078
239 + 8738839 = 8739078
241 + 8738837 = 8739078
269 + 8738809 = 8739078
277 + 8738801 = 8739078
311 + 8738767 = 8739078

Showing the first eight; more decompositions exist.
