Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703142, here are decompositions:

3 + 8703139 = 8703142
5 + 8703137 = 8703142
23 + 8703119 = 8703142
29 + 8703113 = 8703142
53 + 8703089 = 8703142
101 + 8703041 = 8703142
263 + 8702879 = 8703142
389 + 8702753 = 8703142

Showing the first eight; more decompositions exist.
