Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561474, here are decompositions:

13 + 561461 = 561474
97 + 561377 = 561474
101 + 561373 = 561474
107 + 561367 = 561474
127 + 561347 = 561474
131 + 561343 = 561474
167 + 561307 = 561474
197 + 561277 = 561474

Showing the first eight; more decompositions exist.
