Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557842, here are decompositions:

11 + 557831 = 557842
41 + 557801 = 557842
53 + 557789 = 557842
83 + 557759 = 557842
101 + 557741 = 557842
113 + 557729 = 557842
149 + 557693 = 557842
179 + 557663 = 557842

Showing the first eight; more decompositions exist.
