Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557440, here are decompositions:

17 + 557423 = 557440
71 + 557369 = 557440
101 + 557339 = 557440
131 + 557309 = 557440
137 + 557303 = 557440
167 + 557273 = 557440
179 + 557261 = 557440
239 + 557201 = 557440

Showing the first eight; more decompositions exist.
