Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041280, here are decompositions:

11 + 1041269 = 1041280
41 + 1041239 = 1041280
59 + 1041221 = 1041280
113 + 1041167 = 1041280
131 + 1041149 = 1041280
197 + 1041083 = 1041280
239 + 1041041 = 1041280
389 + 1040891 = 1041280

Showing the first eight; more decompositions exist.
