Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 568442, here are decompositions:

3 + 568439 = 568442
79 + 568363 = 568442
139 + 568303 = 568442
163 + 568279 = 568442
211 + 568231 = 568442
241 + 568201 = 568442
271 + 568171 = 568442
373 + 568069 = 568442

Showing the first eight; more decompositions exist.
