Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130908, here are decompositions:

67 + 130841 = 130908
79 + 130829 = 130908
97 + 130811 = 130908
101 + 130807 = 130908
139 + 130769 = 130908
179 + 130729 = 130908
227 + 130681 = 130908
251 + 130657 = 130908

Showing the first eight; more decompositions exist.
