Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031988, here are decompositions:

7 + 1031981 = 1031988
151 + 1031837 = 1031988
157 + 1031831 = 1031988
179 + 1031809 = 1031988
227 + 1031761 = 1031988
229 + 1031759 = 1031988
257 + 1031731 = 1031988
271 + 1031717 = 1031988

Showing the first eight; more decompositions exist.
