Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557418, here are decompositions:

41 + 557377 = 557418
47 + 557371 = 557418
79 + 557339 = 557418
89 + 557329 = 557418
97 + 557321 = 557418
109 + 557309 = 557418
137 + 557281 = 557418
149 + 557269 = 557418

Showing the first eight; more decompositions exist.
