Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571480, here are decompositions:

3 + 571477 = 571480
47 + 571433 = 571480
71 + 571409 = 571480
83 + 571397 = 571480
149 + 571331 = 571480
251 + 571229 = 571480
257 + 571223 = 571480
269 + 571211 = 571480

Showing the first eight; more decompositions exist.
