Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489668, here are decompositions:

17 + 2147489651 = 2147489668
29 + 2147489639 = 2147489668
89 + 2147489579 = 2147489668
131 + 2147489537 = 2147489668
227 + 2147489441 = 2147489668
461 + 2147489207 = 2147489668
761 + 2147488907 = 2147489668
809 + 2147488859 = 2147489668

Showing the first eight; more decompositions exist.
