Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008812, here are decompositions:

3 + 1008809 = 1008812
19 + 1008793 = 1008812
31 + 1008781 = 1008812
199 + 1008613 = 1008812
223 + 1008589 = 1008812
241 + 1008571 = 1008812
271 + 1008541 = 1008812
313 + 1008499 = 1008812

Showing the first eight; more decompositions exist.
