Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006990, here are decompositions:

3 + 1006987 = 1006990
11 + 1006979 = 1006990
41 + 1006949 = 1006990
53 + 1006937 = 1006990
107 + 1006883 = 1006990
113 + 1006877 = 1006990
137 + 1006853 = 1006990
191 + 1006799 = 1006990

Showing the first eight; more decompositions exist.
