Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130786, here are decompositions:

3 + 130783 = 130786
17 + 130769 = 130786
137 + 130649 = 130786
167 + 130619 = 130786
197 + 130589 = 130786
233 + 130553 = 130786
239 + 130547 = 130786
263 + 130523 = 130786

Showing the first eight; more decompositions exist.
