Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008988, here are decompositions:

5 + 1008983 = 1008988
41 + 1008947 = 1008988
131 + 1008857 = 1008988
137 + 1008851 = 1008988
179 + 1008809 = 1008988
269 + 1008719 = 1008988
401 + 1008587 = 1008988
521 + 1008467 = 1008988

Showing the first eight; more decompositions exist.
