Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584876, here are decompositions:

5 + 2147584871 = 2147584876
23 + 2147584853 = 2147584876
29 + 2147584847 = 2147584876
179 + 2147584697 = 2147584876
197 + 2147584679 = 2147584876
347 + 2147584529 = 2147584876
419 + 2147584457 = 2147584876
599 + 2147584277 = 2147584876

Showing the first eight; more decompositions exist.
