Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489170, here are decompositions:

83 + 2147489087 = 2147489170
173 + 2147488997 = 2147489170
251 + 2147488919 = 2147489170
257 + 2147488913 = 2147489170
263 + 2147488907 = 2147489170
311 + 2147488859 = 2147489170
419 + 2147488751 = 2147489170
443 + 2147488727 = 2147489170

Showing the first eight; more decompositions exist.
