Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131498, here are decompositions:

19 + 131479 = 131498
61 + 131437 = 131498
67 + 131431 = 131498
127 + 131371 = 131498
181 + 131317 = 131498
277 + 131221 = 131498
349 + 131149 = 131498
397 + 131101 = 131498

Showing the first eight; more decompositions exist.
