Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571628, here are decompositions:

97 + 571531 = 571628
151 + 571477 = 571628
157 + 571471 = 571628
229 + 571399 = 571628
307 + 571321 = 571628
349 + 571279 = 571628
367 + 571261 = 571628
397 + 571231 = 571628

Showing the first eight; more decompositions exist.
