Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557526, here are decompositions:

5 + 557521 = 557526
7 + 557519 = 557526
37 + 557489 = 557526
43 + 557483 = 557526
83 + 557443 = 557526
103 + 557423 = 557526
149 + 557377 = 557526
157 + 557369 = 557526

Showing the first eight; more decompositions exist.
