Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561674, here are decompositions:

7 + 561667 = 561674
67 + 561607 = 561674
307 + 561367 = 561674
331 + 561343 = 561674
367 + 561307 = 561674
397 + 561277 = 561674
571 + 561103 = 561674
577 + 561097 = 561674

Showing the first eight; more decompositions exist.
