Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008872, here are decompositions:

13 + 1008859 = 1008872
19 + 1008853 = 1008872
43 + 1008829 = 1008872
79 + 1008793 = 1008872
283 + 1008589 = 1008872
331 + 1008541 = 1008872
373 + 1008499 = 1008872
379 + 1008493 = 1008872

Showing the first eight; more decompositions exist.
