Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127830, here are decompositions:

11 + 127819 = 127830
13 + 127817 = 127830
23 + 127807 = 127830
67 + 127763 = 127830
83 + 127747 = 127830
97 + 127733 = 127830
103 + 127727 = 127830
113 + 127717 = 127830

Showing the first eight; more decompositions exist.
