Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019120, here are decompositions:

43 + 1019077 = 1019120
61 + 1019059 = 1019120
97 + 1019023 = 1019120
127 + 1018993 = 1019120
139 + 1018981 = 1019120
163 + 1018957 = 1019120
241 + 1018879 = 1019120
307 + 1018813 = 1019120

Showing the first eight; more decompositions exist.
