Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703920, here are decompositions:

31 + 8703889 = 8703920
61 + 8703859 = 8703920
67 + 8703853 = 8703920
79 + 8703841 = 8703920
97 + 8703823 = 8703920
103 + 8703817 = 8703920
109 + 8703811 = 8703920
139 + 8703781 = 8703920

Showing the first eight; more decompositions exist.
