Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557420, here are decompositions:

43 + 557377 = 557420
139 + 557281 = 557420
151 + 557269 = 557420
223 + 557197 = 557420
379 + 557041 = 557420
421 + 556999 = 557420
433 + 556987 = 557420
439 + 556981 = 557420

Showing the first eight; more decompositions exist.
