Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048864, here are decompositions:

17 + 1048847 = 1048864
71 + 1048793 = 1048864
251 + 1048613 = 1048864
263 + 1048601 = 1048864
281 + 1048583 = 1048864
293 + 1048571 = 1048864
347 + 1048517 = 1048864
431 + 1048433 = 1048864

Showing the first eight; more decompositions exist.
