Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584836, here are decompositions:

29 + 2147584807 = 2147584836
139 + 2147584697 = 2147584836
157 + 2147584679 = 2147584836
167 + 2147584669 = 2147584836
179 + 2147584657 = 2147584836
227 + 2147584609 = 2147584836
233 + 2147584603 = 2147584836
239 + 2147584597 = 2147584836

Showing the first eight; more decompositions exist.
