Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039240, here are decompositions:

11 + 1039229 = 1039240
53 + 1039187 = 1039240
71 + 1039169 = 1039240
101 + 1039139 = 1039240
113 + 1039127 = 1039240
131 + 1039109 = 1039240
173 + 1039067 = 1039240
197 + 1039043 = 1039240

Showing the first eight; more decompositions exist.
