Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101930, here are decompositions:

13 + 101917 = 101930
61 + 101869 = 101930
67 + 101863 = 101930
97 + 101833 = 101930
181 + 101749 = 101930
193 + 101737 = 101930
211 + 101719 = 101930
229 + 101701 = 101930

Showing the first eight; more decompositions exist.
