Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571442, here are decompositions:

43 + 571399 = 571442
61 + 571381 = 571442
73 + 571369 = 571442
103 + 571339 = 571442
139 + 571303 = 571442
163 + 571279 = 571442
181 + 571261 = 571442
211 + 571231 = 571442

Showing the first eight; more decompositions exist.
