Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557438, here are decompositions:

61 + 557377 = 557438
67 + 557371 = 557438
109 + 557329 = 557438
157 + 557281 = 557438
241 + 557197 = 557438
379 + 557059 = 557438
397 + 557041 = 557438
421 + 557017 = 557438

Showing the first eight; more decompositions exist.
