Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018576, here are decompositions:

17 + 1018559 = 1018576
137 + 1018439 = 1018576
239 + 1018337 = 1018576
263 + 1018313 = 1018576
353 + 1018223 = 1018576
359 + 1018217 = 1018576
467 + 1018109 = 1018576
479 + 1018097 = 1018576

Showing the first eight; more decompositions exist.
