Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703520, here are decompositions:

29 + 8703491 = 8703520
131 + 8703389 = 8703520
167 + 8703353 = 8703520
173 + 8703347 = 8703520
227 + 8703293 = 8703520
233 + 8703287 = 8703520
263 + 8703257 = 8703520
347 + 8703173 = 8703520

Showing the first eight; more decompositions exist.
