Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703390, here are decompositions:

11 + 8703379 = 8703390
13 + 8703377 = 8703390
37 + 8703353 = 8703390
43 + 8703347 = 8703390
83 + 8703307 = 8703390
89 + 8703301 = 8703390
97 + 8703293 = 8703390
103 + 8703287 = 8703390

Showing the first eight; more decompositions exist.
