Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123858, here are decompositions:

5 + 123853 = 123858
29 + 123829 = 123858
37 + 123821 = 123858
41 + 123817 = 123858
67 + 123791 = 123858
71 + 123787 = 123858
101 + 123757 = 123858
127 + 123731 = 123858

Showing the first eight; more decompositions exist.
