Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497858, here are decompositions:

89 + 2147497769 = 2147497858
101 + 2147497757 = 2147497858
167 + 2147497691 = 2147497858
197 + 2147497661 = 2147497858
509 + 2147497349 = 2147497858
839 + 2147497019 = 2147497858
887 + 2147496971 = 2147497858
941 + 2147496917 = 2147497858

Showing the first eight; more decompositions exist.
