Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009042, here are decompositions:

5 + 1009037 = 1009042
53 + 1008989 = 1009042
59 + 1008983 = 1009042
131 + 1008911 = 1009042
179 + 1008863 = 1009042
191 + 1008851 = 1009042
233 + 1008809 = 1009042
263 + 1008779 = 1009042

Showing the first eight; more decompositions exist.
