Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571242, here are decompositions:

11 + 571231 = 571242
13 + 571229 = 571242
19 + 571223 = 571242
31 + 571211 = 571242
41 + 571201 = 571242
43 + 571199 = 571242
79 + 571163 = 571242
109 + 571133 = 571242

Showing the first eight; more decompositions exist.
