Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557518, here are decompositions:

29 + 557489 = 557518
149 + 557369 = 557518
179 + 557339 = 557518
197 + 557321 = 557518
257 + 557261 = 557518
317 + 557201 = 557518
359 + 557159 = 557518
431 + 557087 = 557518

Showing the first eight; more decompositions exist.
