Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557242, here are decompositions:

41 + 557201 = 557242
83 + 557159 = 557242
89 + 557153 = 557242
149 + 557093 = 557242
173 + 557069 = 557242
311 + 556931 = 557242
359 + 556883 = 557242
383 + 556859 = 557242

Showing the first eight; more decompositions exist.
