Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561684, here are decompositions:

17 + 561667 = 561684
131 + 561553 = 561684
163 + 561521 = 561684
223 + 561461 = 561684
307 + 561377 = 561684
311 + 561373 = 561684
317 + 561367 = 561684
337 + 561347 = 561684

Showing the first eight; more decompositions exist.
