Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488846, here are decompositions:

53 + 2147488793 = 2147488846
227 + 2147488619 = 2147488846
233 + 2147488613 = 2147488846
599 + 2147488247 = 2147488846
683 + 2147488163 = 2147488846
947 + 2147487899 = 2147488846
977 + 2147487869 = 2147488846
1013 + 2147487833 = 2147488846

Showing the first eight; more decompositions exist.
