Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009240, here are decompositions:

3 + 1009237 = 1009240
41 + 1009199 = 1009240
47 + 1009193 = 1009240
83 + 1009157 = 1009240
101 + 1009139 = 1009240
179 + 1009061 = 1009240
191 + 1009049 = 1009240
233 + 1009007 = 1009240

Showing the first eight; more decompositions exist.
