Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488322, here are decompositions:

43 + 2147488279 = 2147488322
73 + 2147488249 = 2147488322
151 + 2147488171 = 2147488322
211 + 2147488111 = 2147488322
313 + 2147488009 = 2147488322
523 + 2147487799 = 2147488322
541 + 2147487781 = 2147488322
571 + 2147487751 = 2147488322

Showing the first eight; more decompositions exist.
