Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008680, here are decompositions:

67 + 1008613 = 1008680
73 + 1008607 = 1008680
109 + 1008571 = 1008680
139 + 1008541 = 1008680
163 + 1008517 = 1008680
181 + 1008499 = 1008680
229 + 1008451 = 1008680
271 + 1008409 = 1008680

Showing the first eight; more decompositions exist.
