Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540740, here are decompositions:

37 + 540703 = 540740
43 + 540697 = 540740
61 + 540679 = 540740
127 + 540613 = 540740
163 + 540577 = 540740
181 + 540559 = 540740
199 + 540541 = 540740
223 + 540517 = 540740

Showing the first eight; more decompositions exist.
