Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557890, here are decompositions:

29 + 557861 = 557890
59 + 557831 = 557890
89 + 557801 = 557890
101 + 557789 = 557890
131 + 557759 = 557890
149 + 557741 = 557890
173 + 557717 = 557890
197 + 557693 = 557890

Showing the first eight; more decompositions exist.
