Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557730, here are decompositions:

13 + 557717 = 557730
37 + 557693 = 557730
59 + 557671 = 557730
67 + 557663 = 557730
97 + 557633 = 557730
139 + 557591 = 557730
157 + 557573 = 557730
163 + 557567 = 557730

Showing the first eight; more decompositions exist.
