Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042988, here are decompositions:

127 + 1042861 = 1042988
139 + 1042849 = 1042988
151 + 1042837 = 1042988
229 + 1042759 = 1042988
307 + 1042681 = 1042988
379 + 1042609 = 1042988
607 + 1042381 = 1042988
619 + 1042369 = 1042988

Showing the first eight; more decompositions exist.
