Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561202, here are decompositions:

3 + 561199 = 561202
11 + 561191 = 561202
29 + 561173 = 561202
41 + 561161 = 561202
101 + 561101 = 561202
149 + 561053 = 561202
233 + 560969 = 561202
263 + 560939 = 561202

Showing the first eight; more decompositions exist.
