Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557222, here are decompositions:

163 + 557059 = 557222
181 + 557041 = 557222
223 + 556999 = 557222
241 + 556981 = 557222
283 + 556939 = 557222
331 + 556891 = 557222
373 + 556849 = 557222
433 + 556789 = 557222

Showing the first eight; more decompositions exist.
