Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738144, here are decompositions:

43 + 8738101 = 8738144
61 + 8738083 = 8738144
73 + 8738071 = 8738144
97 + 8738047 = 8738144
211 + 8737933 = 8738144
223 + 8737921 = 8738144
271 + 8737873 = 8738144
277 + 8737867 = 8738144

Showing the first eight; more decompositions exist.
