Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497986, here are decompositions:

37 + 2147497949 = 2147497986
43 + 2147497943 = 2147497986
47 + 2147497939 = 2147497986
79 + 2147497907 = 2147497986
97 + 2147497889 = 2147497986
229 + 2147497757 = 2147497986
269 + 2147497717 = 2147497986
463 + 2147497523 = 2147497986

Showing the first eight; more decompositions exist.
