Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561586, here are decompositions:

167 + 561419 = 561586
197 + 561389 = 561586
227 + 561359 = 561586
239 + 561347 = 561586
503 + 561083 = 561586
617 + 560969 = 561586
647 + 560939 = 561586
947 + 560639 = 561586

Showing the first eight; more decompositions exist.
