Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485982, here are decompositions:

13 + 2147485969 = 2147485982
43 + 2147485939 = 2147485982
139 + 2147485843 = 2147485982
163 + 2147485819 = 2147485982
223 + 2147485759 = 2147485982
409 + 2147485573 = 2147485982
571 + 2147485411 = 2147485982
601 + 2147485381 = 2147485982

Showing the first eight; more decompositions exist.
