Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703878, here are decompositions:

19 + 8703859 = 8703878
37 + 8703841 = 8703878
61 + 8703817 = 8703878
67 + 8703811 = 8703878
97 + 8703781 = 8703878
367 + 8703511 = 8703878
397 + 8703481 = 8703878
499 + 8703379 = 8703878

Showing the first eight; more decompositions exist.
