Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021740, here are decompositions:

29 + 1021711 = 1021740
43 + 1021697 = 1021740
67 + 1021673 = 1021740
79 + 1021661 = 1021740
89 + 1021651 = 1021740
113 + 1021627 = 1021740
163 + 1021577 = 1021740
179 + 1021561 = 1021740

Showing the first eight; more decompositions exist.
