Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561478, here are decompositions:

17 + 561461 = 561478
59 + 561419 = 561478
89 + 561389 = 561478
101 + 561377 = 561478
131 + 561347 = 561478
227 + 561251 = 561478
317 + 561161 = 561478
419 + 561059 = 561478

Showing the first eight; more decompositions exist.
