Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045986, here are decompositions:

5 + 1045981 = 1045986
23 + 1045963 = 1045986
79 + 1045907 = 1045986
83 + 1045903 = 1045986
127 + 1045859 = 1045986
157 + 1045829 = 1045986
167 + 1045819 = 1045986
223 + 1045763 = 1045986

Showing the first eight; more decompositions exist.
