Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012988, here are decompositions:

7 + 1012981 = 1012988
127 + 1012861 = 1012988
157 + 1012831 = 1012988
199 + 1012789 = 1012988
271 + 1012717 = 1012988
331 + 1012657 = 1012988
397 + 1012591 = 1012988
439 + 1012549 = 1012988

Showing the first eight; more decompositions exist.
