Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489686, here are decompositions:

47 + 2147489639 = 2147489686
107 + 2147489579 = 2147489686
149 + 2147489537 = 2147489686
263 + 2147489423 = 2147489686
389 + 2147489297 = 2147489686
443 + 2147489243 = 2147489686
479 + 2147489207 = 2147489686
599 + 2147489087 = 2147489686

Showing the first eight; more decompositions exist.
