Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739144, here are decompositions:

17 + 8739127 = 8739144
31 + 8739113 = 8739144
47 + 8739097 = 8739144
137 + 8739007 = 8739144
181 + 8738963 = 8739144
263 + 8738881 = 8739144
307 + 8738837 = 8739144
331 + 8738813 = 8739144

Showing the first eight; more decompositions exist.
