Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130744, here are decompositions:

101 + 130643 = 130744
113 + 130631 = 130744
191 + 130553 = 130744
197 + 130547 = 130744
227 + 130517 = 130744
401 + 130343 = 130744
491 + 130253 = 130744
503 + 130241 = 130744

Showing the first eight; more decompositions exist.
