Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019240, here are decompositions:

3 + 1019237 = 1019240
31 + 1019209 = 1019240
43 + 1019197 = 1019240
67 + 1019173 = 1019240
163 + 1019077 = 1019240
181 + 1019059 = 1019240
241 + 1018999 = 1019240
283 + 1018957 = 1019240

Showing the first eight; more decompositions exist.
