Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011998, here are decompositions:

19 + 1011979 = 1011998
37 + 1011961 = 1011998
61 + 1011937 = 1011998
109 + 1011889 = 1011998
181 + 1011817 = 1011998
199 + 1011799 = 1011998
331 + 1011667 = 1011998
349 + 1011649 = 1011998

Showing the first eight; more decompositions exist.
