Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024720, here are decompositions:

17 + 1024703 = 1024720
23 + 1024697 = 1024720
131 + 1024589 = 1024720
173 + 1024547 = 1024720
197 + 1024523 = 1024720
239 + 1024481 = 1024720
293 + 1024427 = 1024720
383 + 1024337 = 1024720

Showing the first eight; more decompositions exist.
