Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008860, here are decompositions:

3 + 1008857 = 1008860
7 + 1008853 = 1008860
31 + 1008829 = 1008860
43 + 1008817 = 1008860
67 + 1008793 = 1008860
79 + 1008781 = 1008860
271 + 1008589 = 1008860
313 + 1008547 = 1008860

Showing the first eight; more decompositions exist.
