Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738272, here are decompositions:

41 + 8738231 = 8738272
71 + 8738201 = 8738272
149 + 8738123 = 8738272
239 + 8738033 = 8738272
293 + 8737979 = 8738272
401 + 8737871 = 8738272
443 + 8737829 = 8738272
509 + 8737763 = 8738272

Showing the first eight; more decompositions exist.
