Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489984, here are decompositions:

37 + 2147489947 = 2147489984
43 + 2147489941 = 2147489984
67 + 2147489917 = 2147489984
163 + 2147489821 = 2147489984
271 + 2147489713 = 2147489984
331 + 2147489653 = 2147489984
397 + 2147489587 = 2147489984
547 + 2147489437 = 2147489984

Showing the first eight; more decompositions exist.
