Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500740, here are decompositions:

11 + 500729 = 500740
17 + 500723 = 500740
41 + 500699 = 500740
47 + 500693 = 500740
137 + 500603 = 500740
173 + 500567 = 500740
239 + 500501 = 500740
257 + 500483 = 500740

Showing the first eight; more decompositions exist.
