Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123830, here are decompositions:

13 + 123817 = 123830
43 + 123787 = 123830
73 + 123757 = 123830
97 + 123733 = 123830
103 + 123727 = 123830
163 + 123667 = 123830
193 + 123637 = 123830
199 + 123631 = 123830

Showing the first eight; more decompositions exist.
