Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489398, here are decompositions:

101 + 2147489297 = 2147489398
107 + 2147489291 = 2147489398
191 + 2147489207 = 2147489398
311 + 2147489087 = 2147489398
401 + 2147488997 = 2147489398
479 + 2147488919 = 2147489398
491 + 2147488907 = 2147489398
647 + 2147488751 = 2147489398

Showing the first eight; more decompositions exist.
