Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703440, here are decompositions:

13 + 8703427 = 8703440
37 + 8703403 = 8703440
61 + 8703379 = 8703440
139 + 8703301 = 8703440
157 + 8703283 = 8703440
199 + 8703241 = 8703440
349 + 8703091 = 8703440
379 + 8703061 = 8703440

Showing the first eight; more decompositions exist.
