Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049990, here are decompositions:

13 + 1049977 = 1049990
37 + 1049953 = 1049990
127 + 1049863 = 1049990
157 + 1049833 = 1049990
163 + 1049827 = 1049990
181 + 1049809 = 1049990
199 + 1049791 = 1049990
283 + 1049707 = 1049990

Showing the first eight; more decompositions exist.
