Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561130, here are decompositions:

29 + 561101 = 561130
47 + 561083 = 561130
71 + 561059 = 561130
83 + 561047 = 561130
191 + 560939 = 561130
233 + 560897 = 561130
239 + 560891 = 561130
257 + 560873 = 561130

Showing the first eight; more decompositions exist.
