Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561136, here are decompositions:

53 + 561083 = 561136
83 + 561053 = 561136
89 + 561047 = 561136
167 + 560969 = 561136
197 + 560939 = 561136
239 + 560897 = 561136
263 + 560873 = 561136
353 + 560783 = 561136

Showing the first eight; more decompositions exist.
