Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1053990, here are decompositions:

19 + 1053971 = 1053990
23 + 1053967 = 1053990
31 + 1053959 = 1053990
37 + 1053953 = 1053990
127 + 1053863 = 1053990
163 + 1053827 = 1053990
173 + 1053817 = 1053990
181 + 1053809 = 1053990

Showing the first eight; more decompositions exist.
