Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561282, here are decompositions:

5 + 561277 = 561282
31 + 561251 = 561282
53 + 561229 = 561282
83 + 561199 = 561282
101 + 561181 = 561282
109 + 561173 = 561282
173 + 561109 = 561282
179 + 561103 = 561282

Showing the first eight; more decompositions exist.
