Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561040, here are decompositions:

71 + 560969 = 561040
101 + 560939 = 561040
149 + 560891 = 561040
167 + 560873 = 561040
257 + 560783 = 561040
269 + 560771 = 561040
401 + 560639 = 561040
419 + 560621 = 561040

Showing the first eight; more decompositions exist.
