Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123812, here are decompositions:

79 + 123733 = 123812
151 + 123661 = 123812
181 + 123631 = 123812
193 + 123619 = 123812
211 + 123601 = 123812
229 + 123583 = 123812
313 + 123499 = 123812
373 + 123439 = 123812

Showing the first eight; more decompositions exist.
