Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130788, here are decompositions:

5 + 130783 = 130788
19 + 130769 = 130788
59 + 130729 = 130788
89 + 130699 = 130788
101 + 130687 = 130788
107 + 130681 = 130788
131 + 130657 = 130788
137 + 130651 = 130788

Showing the first eight; more decompositions exist.
