Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484538, here are decompositions:

11 + 2147484527 = 2147484538
47 + 2147484491 = 2147484538
317 + 2147484221 = 2147484538
587 + 2147483951 = 2147484538
761 + 2147483777 = 2147484538
1049 + 2147483489 = 2147484538
1061 + 2147483477 = 2147484538
1289 + 2147483249 = 2147484538

Showing the first eight; more decompositions exist.
