Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019180, here are decompositions:

3 + 1019177 = 1019180
7 + 1019173 = 1019180
61 + 1019119 = 1019180
103 + 1019077 = 1019180
109 + 1019071 = 1019180
157 + 1019023 = 1019180
181 + 1018999 = 1019180
193 + 1018987 = 1019180

Showing the first eight; more decompositions exist.
