Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561484, here are decompositions:

23 + 561461 = 561484
107 + 561377 = 561484
137 + 561347 = 561484
233 + 561251 = 561484
293 + 561191 = 561484
311 + 561173 = 561484
383 + 561101 = 561484
401 + 561083 = 561484

Showing the first eight; more decompositions exist.
