Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473028, here are decompositions:

241 + 2147472787 = 2147473028
271 + 2147472757 = 2147473028
277 + 2147472751 = 2147473028
331 + 2147472697 = 2147473028
607 + 2147472421 = 2147473028
739 + 2147472289 = 2147473028
769 + 2147472259 = 2147473028
829 + 2147472199 = 2147473028

Showing the first eight; more decompositions exist.
