Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045740, here are decompositions:

11 + 1045729 = 1045740
13 + 1045727 = 1045740
61 + 1045679 = 1045740
89 + 1045651 = 1045740
97 + 1045643 = 1045740
107 + 1045633 = 1045740
167 + 1045573 = 1045740
181 + 1045559 = 1045740

Showing the first eight; more decompositions exist.
