Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703428, here are decompositions:

127 + 8703301 = 8703428
277 + 8703151 = 8703428
337 + 8703091 = 8703428
367 + 8703061 = 8703428
439 + 8702989 = 8703428
607 + 8702821 = 8703428
739 + 8702689 = 8703428
859 + 8702569 = 8703428

Showing the first eight; more decompositions exist.
