Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571742, here are decompositions:

43 + 571699 = 571742
109 + 571633 = 571742
139 + 571603 = 571742
163 + 571579 = 571742
211 + 571531 = 571742
271 + 571471 = 571742
373 + 571369 = 571742
421 + 571321 = 571742

Showing the first eight; more decompositions exist.
