Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488956, here are decompositions:

37 + 2147488919 = 2147488956
43 + 2147488913 = 2147488956
89 + 2147488867 = 2147488956
97 + 2147488859 = 2147488956
163 + 2147488793 = 2147488956
229 + 2147488727 = 2147488956
313 + 2147488643 = 2147488956
337 + 2147488619 = 2147488956

Showing the first eight; more decompositions exist.
