Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130508, here are decompositions:

19 + 130489 = 130508
31 + 130477 = 130508
61 + 130447 = 130508
97 + 130411 = 130508
109 + 130399 = 130508
139 + 130369 = 130508
229 + 130279 = 130508
241 + 130267 = 130508

Showing the first eight; more decompositions exist.
