Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561404, here are decompositions:

31 + 561373 = 561404
37 + 561367 = 561404
61 + 561343 = 561404
97 + 561307 = 561404
127 + 561277 = 561404
223 + 561181 = 561404
307 + 561097 = 561404
313 + 561091 = 561404

Showing the first eight; more decompositions exist.
