Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008578, here are decompositions:

7 + 1008571 = 1008578
31 + 1008547 = 1008578
37 + 1008541 = 1008578
61 + 1008517 = 1008578
79 + 1008499 = 1008578
127 + 1008451 = 1008578
157 + 1008421 = 1008578
199 + 1008379 = 1008578

Showing the first eight; more decompositions exist.
