Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118830, here are decompositions:

11 + 118819 = 118830
29 + 118801 = 118830
31 + 118799 = 118830
43 + 118787 = 118830
73 + 118757 = 118830
79 + 118751 = 118830
83 + 118747 = 118830
113 + 118717 = 118830

Showing the first eight; more decompositions exist.
