Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029740, here are decompositions:

43 + 1029697 = 1029740
97 + 1029643 = 1029740
139 + 1029601 = 1029740
157 + 1029583 = 1029740
163 + 1029577 = 1029740
193 + 1029547 = 1029740
223 + 1029517 = 1029740
241 + 1029499 = 1029740

Showing the first eight; more decompositions exist.
