Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008830, here are decompositions:

13 + 1008817 = 1008830
37 + 1008793 = 1008830
223 + 1008607 = 1008830
241 + 1008589 = 1008830
283 + 1008547 = 1008830
313 + 1008517 = 1008830
331 + 1008499 = 1008830
337 + 1008493 = 1008830

Showing the first eight; more decompositions exist.
