Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488872, here are decompositions:

5 + 2147488867 = 2147488872
13 + 2147488859 = 2147488872
79 + 2147488793 = 2147488872
131 + 2147488741 = 2147488872
181 + 2147488691 = 2147488872
229 + 2147488643 = 2147488872
293 + 2147488579 = 2147488872
313 + 2147488559 = 2147488872

Showing the first eight; more decompositions exist.
