Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752278, here are decompositions:

5 + 8752273 = 8752278
47 + 8752231 = 8752278
71 + 8752207 = 8752278
97 + 8752181 = 8752278
149 + 8752129 = 8752278
211 + 8752067 = 8752278
239 + 8752039 = 8752278
347 + 8751931 = 8752278

Showing the first eight; more decompositions exist.
