Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561342, here are decompositions:

29 + 561313 = 561342
113 + 561229 = 561342
151 + 561191 = 561342
181 + 561161 = 561342
233 + 561109 = 561342
239 + 561103 = 561342
241 + 561101 = 561342
251 + 561091 = 561342

Showing the first eight; more decompositions exist.
