Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732320, here are decompositions:

11 + 8732309 = 8732320
29 + 8732291 = 8732320
59 + 8732261 = 8732320
131 + 8732189 = 8732320
197 + 8732123 = 8732320
227 + 8732093 = 8732320
239 + 8732081 = 8732320
269 + 8732051 = 8732320

Showing the first eight; more decompositions exist.
