Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472998, here are decompositions:

211 + 2147472787 = 2147472998
241 + 2147472757 = 2147472998
397 + 2147472601 = 2147472998
499 + 2147472499 = 2147472998
577 + 2147472421 = 2147472998
709 + 2147472289 = 2147472998
739 + 2147472259 = 2147472998
907 + 2147472091 = 2147472998

Showing the first eight; more decompositions exist.
