Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561356, here are decompositions:

13 + 561343 = 561356
43 + 561313 = 561356
79 + 561277 = 561356
127 + 561229 = 561356
157 + 561199 = 561356
277 + 561079 = 561356
337 + 561019 = 561356
379 + 560977 = 561356

Showing the first eight; more decompositions exist.
