Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489678, here are decompositions:

241 + 2147489437 = 2147489678
277 + 2147489401 = 2147489678
331 + 2147489347 = 2147489678
379 + 2147489299 = 2147489678
601 + 2147489077 = 2147489678
619 + 2147489059 = 2147489678
661 + 2147489017 = 2147489678
811 + 2147488867 = 2147489678

Showing the first eight; more decompositions exist.
