Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561260, here are decompositions:

31 + 561229 = 561260
61 + 561199 = 561260
79 + 561181 = 561260
151 + 561109 = 561260
157 + 561103 = 561260
163 + 561097 = 561260
181 + 561079 = 561260
199 + 561061 = 561260

Showing the first eight; more decompositions exist.
