Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561670, here are decompositions:

3 + 561667 = 561670
71 + 561599 = 561670
149 + 561521 = 561670
251 + 561419 = 561670
281 + 561389 = 561670
293 + 561377 = 561670
311 + 561359 = 561670
419 + 561251 = 561670

Showing the first eight; more decompositions exist.
