Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043890, here are decompositions:

17 + 1043873 = 1043890
41 + 1043849 = 1043890
47 + 1043843 = 1043890
53 + 1043837 = 1043890
59 + 1043831 = 1043890
131 + 1043759 = 1043890
137 + 1043753 = 1043890
167 + 1043723 = 1043890

Showing the first eight; more decompositions exist.
