Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019988, here are decompositions:

17 + 1019971 = 1019988
61 + 1019927 = 1019988
89 + 1019899 = 1019988
127 + 1019861 = 1019988
131 + 1019857 = 1019988
139 + 1019849 = 1019988
149 + 1019839 = 1019988
241 + 1019747 = 1019988

Showing the first eight; more decompositions exist.
