Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123876, here are decompositions:

13 + 123863 = 123876
23 + 123853 = 123876
43 + 123833 = 123876
47 + 123829 = 123876
59 + 123817 = 123876
73 + 123803 = 123876
89 + 123787 = 123876
139 + 123737 = 123876

Showing the first eight; more decompositions exist.
