Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489372, here are decompositions:

73 + 2147489299 = 2147489372
109 + 2147489263 = 2147489372
229 + 2147489143 = 2147489372
283 + 2147489089 = 2147489372
313 + 2147489059 = 2147489372
349 + 2147489023 = 2147489372
631 + 2147488741 = 2147489372
829 + 2147488543 = 2147489372

Showing the first eight; more decompositions exist.
