Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561230, here are decompositions:

31 + 561199 = 561230
127 + 561103 = 561230
139 + 561091 = 561230
151 + 561079 = 561230
211 + 561019 = 561230
337 + 560893 = 561230
367 + 560863 = 561230
433 + 560797 = 561230

Showing the first eight; more decompositions exist.
