Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557740, here are decompositions:

11 + 557729 = 557740
23 + 557717 = 557740
47 + 557693 = 557740
101 + 557639 = 557740
107 + 557633 = 557740
149 + 557591 = 557740
167 + 557573 = 557740
173 + 557567 = 557740

Showing the first eight; more decompositions exist.
