Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709144, here are decompositions:

5 + 8709139 = 8709144
11 + 8709133 = 8709144
23 + 8709121 = 8709144
137 + 8709007 = 8709144
173 + 8708971 = 8709144
181 + 8708963 = 8709144
233 + 8708911 = 8709144
251 + 8708893 = 8709144

Showing the first eight; more decompositions exist.
