Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709232, here are decompositions:

3 + 8709229 = 8709232
11 + 8709221 = 8709232
41 + 8709191 = 8709232
83 + 8709149 = 8709232
173 + 8709059 = 8709232
263 + 8708969 = 8709232
269 + 8708963 = 8709232
383 + 8708849 = 8709232

Showing the first eight; more decompositions exist.
