Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561672, here are decompositions:

5 + 561667 = 561672
73 + 561599 = 561672
113 + 561559 = 561672
151 + 561521 = 561672
211 + 561461 = 561672
233 + 561439 = 561672
263 + 561409 = 561672
283 + 561389 = 561672

Showing the first eight; more decompositions exist.
