Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019008, here are decompositions:

41 + 1018967 = 1019008
59 + 1018949 = 1019008
71 + 1018937 = 1019008
101 + 1018907 = 1019008
149 + 1018859 = 1019008
191 + 1018817 = 1019008
197 + 1018811 = 1019008
239 + 1018769 = 1019008

Showing the first eight; more decompositions exist.
