Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130126, here are decompositions:

5 + 130121 = 130126
47 + 130079 = 130126
53 + 130073 = 130126
83 + 130043 = 130126
167 + 129959 = 130126
173 + 129953 = 130126
233 + 129893 = 130126
239 + 129887 = 130126

Showing the first eight; more decompositions exist.
