Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561322, here are decompositions:

71 + 561251 = 561322
131 + 561191 = 561322
149 + 561173 = 561322
239 + 561083 = 561322
263 + 561059 = 561322
269 + 561053 = 561322
353 + 560969 = 561322
383 + 560939 = 561322

Showing the first eight; more decompositions exist.
