Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130928, here are decompositions:

199 + 130729 = 130928
229 + 130699 = 130928
241 + 130687 = 130928
271 + 130657 = 130928
277 + 130651 = 130928
307 + 130621 = 130928
349 + 130579 = 130928
397 + 130531 = 130928

Showing the first eight; more decompositions exist.
