Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497756, here are decompositions:

23 + 2147497733 = 2147497756
59 + 2147497697 = 2147497756
197 + 2147497559 = 2147497756
233 + 2147497523 = 2147497756
263 + 2147497493 = 2147497756
353 + 2147497403 = 2147497756
839 + 2147496917 = 2147497756
977 + 2147496779 = 2147497756

Showing the first eight; more decompositions exist.
