Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1041640, here are decompositions:

23 + 1041617 = 1041640
179 + 1041461 = 1041640
191 + 1041449 = 1041640
311 + 1041329 = 1041640
359 + 1041281 = 1041640
401 + 1041239 = 1041640
419 + 1041221 = 1041640
491 + 1041149 = 1041640

Showing the first eight; more decompositions exist.
