Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561408, here are decompositions:

19 + 561389 = 561408
31 + 561377 = 561408
41 + 561367 = 561408
61 + 561347 = 561408
101 + 561307 = 561408
131 + 561277 = 561408
157 + 561251 = 561408
179 + 561229 = 561408

Showing the first eight; more decompositions exist.
