Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008800, here are decompositions:

7 + 1008793 = 1008800
19 + 1008781 = 1008800
193 + 1008607 = 1008800
211 + 1008589 = 1008800
229 + 1008571 = 1008800
283 + 1008517 = 1008800
307 + 1008493 = 1008800
349 + 1008451 = 1008800

Showing the first eight; more decompositions exist.
