Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493470, here are decompositions:

13 + 2147493457 = 2147493470
37 + 2147493433 = 2147493470
61 + 2147493409 = 2147493470
79 + 2147493391 = 2147493470
181 + 2147493289 = 2147493470
193 + 2147493277 = 2147493470
229 + 2147493241 = 2147493470
433 + 2147493037 = 2147493470

Showing the first eight; more decompositions exist.
