Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130750, here are decompositions:

101 + 130649 = 130750
107 + 130643 = 130750
131 + 130619 = 130750
197 + 130553 = 130750
227 + 130523 = 130750
233 + 130517 = 130750
281 + 130469 = 130750
293 + 130457 = 130750

Showing the first eight; more decompositions exist.
