Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1032640, here are decompositions:

23 + 1032617 = 1032640
113 + 1032527 = 1032640
131 + 1032509 = 1032640
149 + 1032491 = 1032640
173 + 1032467 = 1032640
233 + 1032407 = 1032640
263 + 1032377 = 1032640
293 + 1032347 = 1032640

Showing the first eight; more decompositions exist.
