Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561718, here are decompositions:

5 + 561713 = 561718
167 + 561551 = 561718
197 + 561521 = 561718
257 + 561461 = 561718
359 + 561359 = 561718
467 + 561251 = 561718
557 + 561161 = 561718
617 + 561101 = 561718

Showing the first eight; more decompositions exist.
