Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1064720, here are decompositions:

31 + 1064689 = 1064720
67 + 1064653 = 1064720
127 + 1064593 = 1064720
199 + 1064521 = 1064720
313 + 1064407 = 1064720
337 + 1064383 = 1064720
379 + 1064341 = 1064720
409 + 1064311 = 1064720

Showing the first eight; more decompositions exist.
