Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130940, here are decompositions:

13 + 130927 = 130940
67 + 130873 = 130940
97 + 130843 = 130940
157 + 130783 = 130940
211 + 130729 = 130940
241 + 130699 = 130940
283 + 130657 = 130940
307 + 130633 = 130940

Showing the first eight; more decompositions exist.
