Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123976, here are decompositions:

3 + 123973 = 123976
23 + 123953 = 123976
53 + 123923 = 123976
89 + 123887 = 123976
113 + 123863 = 123976
173 + 123803 = 123976
239 + 123737 = 123976
257 + 123719 = 123976

Showing the first eight; more decompositions exist.
