Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123926, here are decompositions:

3 + 123923 = 123926
73 + 123853 = 123926
97 + 123829 = 123926
109 + 123817 = 123926
139 + 123787 = 123926
193 + 123733 = 123926
199 + 123727 = 123926
307 + 123619 = 123926

Showing the first eight; more decompositions exist.
