Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130180, here are decompositions:

53 + 130127 = 130180
59 + 130121 = 130180
101 + 130079 = 130180
107 + 130073 = 130180
137 + 130043 = 130180
227 + 129953 = 130180
263 + 129917 = 130180
293 + 129887 = 130180

Showing the first eight; more decompositions exist.
