Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561468, here are decompositions:

7 + 561461 = 561468
29 + 561439 = 561468
59 + 561409 = 561468
79 + 561389 = 561468
101 + 561367 = 561468
109 + 561359 = 561468
191 + 561277 = 561468
239 + 561229 = 561468

Showing the first eight; more decompositions exist.
