Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709240, here are decompositions:

11 + 8709229 = 8709240
19 + 8709221 = 8709240
53 + 8709187 = 8709240
101 + 8709139 = 8709240
107 + 8709133 = 8709240
173 + 8709067 = 8709240
181 + 8709059 = 8709240
233 + 8709007 = 8709240

Showing the first eight; more decompositions exist.
