Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123300, here are decompositions:

11 + 123289 = 123300
31 + 123269 = 123300
41 + 123259 = 123300
61 + 123239 = 123300
71 + 123229 = 123300
83 + 123217 = 123300
97 + 123203 = 123300
109 + 123191 = 123300

Showing the first eight; more decompositions exist.
