Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561406, here are decompositions:

17 + 561389 = 561406
29 + 561377 = 561406
47 + 561359 = 561406
59 + 561347 = 561406
233 + 561173 = 561406
347 + 561059 = 561406
353 + 561053 = 561406
359 + 561047 = 561406

Showing the first eight; more decompositions exist.
