Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561772, here are decompositions:

5 + 561767 = 561772
11 + 561761 = 561772
59 + 561713 = 561772
173 + 561599 = 561772
251 + 561521 = 561772
311 + 561461 = 561772
353 + 561419 = 561772
383 + 561389 = 561772

Showing the first eight; more decompositions exist.
