Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739072, here are decompositions:

19 + 8739053 = 8739072
71 + 8739001 = 8739072
109 + 8738963 = 8739072
191 + 8738881 = 8739072
229 + 8738843 = 8739072
233 + 8738839 = 8739072
263 + 8738809 = 8739072
271 + 8738801 = 8739072

Showing the first eight; more decompositions exist.
