Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485412, here are decompositions:

31 + 2147485381 = 2147485412
43 + 2147485369 = 2147485412
103 + 2147485309 = 2147485412
151 + 2147485261 = 2147485412
211 + 2147485201 = 2147485412
223 + 2147485189 = 2147485412
271 + 2147485141 = 2147485412
421 + 2147484991 = 2147485412

Showing the first eight; more decompositions exist.
