Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492882, here are decompositions:

181 + 2147492701 = 2147492882
211 + 2147492671 = 2147492882
229 + 2147492653 = 2147492882
331 + 2147492551 = 2147492882
349 + 2147492533 = 2147492882
643 + 2147492239 = 2147492882
853 + 2147492029 = 2147492882
859 + 2147492023 = 2147492882

Showing the first eight; more decompositions exist.
