Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571280, here are decompositions:

13 + 571267 = 571280
19 + 571261 = 571280
79 + 571201 = 571280
181 + 571099 = 571280
211 + 571069 = 571280
313 + 570967 = 571280
331 + 570949 = 571280
379 + 570901 = 571280

Showing the first eight; more decompositions exist.
