Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130138, here are decompositions:

11 + 130127 = 130138
17 + 130121 = 130138
59 + 130079 = 130138
167 + 129971 = 130138
179 + 129959 = 130138
251 + 129887 = 130138
389 + 129749 = 130138
401 + 129737 = 130138

Showing the first eight; more decompositions exist.
