Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045100, here are decompositions:

19 + 1045081 = 1045100
37 + 1045063 = 1045100
73 + 1045027 = 1045100
79 + 1045021 = 1045100
97 + 1045003 = 1045100
103 + 1044997 = 1045100
211 + 1044889 = 1045100
223 + 1044877 = 1045100

Showing the first eight; more decompositions exist.
