Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571490, here are decompositions:

13 + 571477 = 571490
19 + 571471 = 571490
37 + 571453 = 571490
109 + 571381 = 571490
151 + 571339 = 571490
211 + 571279 = 571490
223 + 571267 = 571490
229 + 571261 = 571490

Showing the first eight; more decompositions exist.
