Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561274, here are decompositions:

23 + 561251 = 561274
83 + 561191 = 561274
101 + 561173 = 561274
113 + 561161 = 561274
173 + 561101 = 561274
191 + 561083 = 561274
227 + 561047 = 561274
383 + 560891 = 561274

Showing the first eight; more decompositions exist.
