Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738072, here are decompositions:

19 + 8738053 = 8738072
61 + 8738011 = 8738072
139 + 8737933 = 8738072
151 + 8737921 = 8738072
199 + 8737873 = 8738072
223 + 8737849 = 8738072
229 + 8737843 = 8738072
271 + 8737801 = 8738072

Showing the first eight; more decompositions exist.
