Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472686, here are decompositions:

3 + 2147472683 = 2147472686
313 + 2147472373 = 2147472686
397 + 2147472289 = 2147472686
487 + 2147472199 = 2147472686
577 + 2147472109 = 2147472686
643 + 2147472043 = 2147472686
823 + 2147471863 = 2147472686
1039 + 2147471647 = 2147472686

Showing the first eight; more decompositions exist.
