Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008728, here are decompositions:

139 + 1008589 = 1008728
157 + 1008571 = 1008728
181 + 1008547 = 1008728
211 + 1008517 = 1008728
229 + 1008499 = 1008728
277 + 1008451 = 1008728
307 + 1008421 = 1008728
349 + 1008379 = 1008728

Showing the first eight; more decompositions exist.
