Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555740, here are decompositions:

43 + 555697 = 555740
79 + 555661 = 555740
103 + 555637 = 555740
151 + 555589 = 555740
349 + 555391 = 555740
379 + 555361 = 555740
433 + 555307 = 555740
439 + 555301 = 555740

Showing the first eight; more decompositions exist.
