Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489882, here are decompositions:

61 + 2147489821 = 2147489882
229 + 2147489653 = 2147489882
379 + 2147489503 = 2147489882
409 + 2147489473 = 2147489882
619 + 2147489263 = 2147489882
739 + 2147489143 = 2147489882
823 + 2147489059 = 2147489882
859 + 2147489023 = 2147489882

Showing the first eight; more decompositions exist.
