Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561676, here are decompositions:

257 + 561419 = 561676
317 + 561359 = 561676
503 + 561173 = 561676
593 + 561083 = 561676
617 + 561059 = 561676
839 + 560837 = 561676
1187 + 560489 = 561676
1217 + 560459 = 561676

Showing the first eight; more decompositions exist.
