Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050990, here are decompositions:

13 + 1050977 = 1050990
29 + 1050961 = 1050990
41 + 1050949 = 1050990
89 + 1050901 = 1050990
103 + 1050887 = 1050990
137 + 1050853 = 1050990
139 + 1050851 = 1050990
173 + 1050817 = 1050990

Showing the first eight; more decompositions exist.
