Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124830, here are decompositions:

7 + 124823 = 124830
11 + 124819 = 124830
31 + 124799 = 124830
37 + 124793 = 124830
47 + 124783 = 124830
53 + 124777 = 124830
59 + 124771 = 124830
61 + 124769 = 124830

Showing the first eight; more decompositions exist.
