Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571564, here are decompositions:

23 + 571541 = 571564
131 + 571433 = 571564
167 + 571397 = 571564
233 + 571331 = 571564
353 + 571211 = 571564
401 + 571163 = 571564
431 + 571133 = 571564
563 + 571001 = 571564

Showing the first eight; more decompositions exist.
