Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29980, here are decompositions:

53 + 29927 = 29980
59 + 29921 = 29980
101 + 29879 = 29980
107 + 29873 = 29980
113 + 29867 = 29980
191 + 29789 = 29980
227 + 29753 = 29980
239 + 29741 = 29980

Showing the first eight; more decompositions exist.
