Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584764, here are decompositions:

67 + 2147584697 = 2147584764
71 + 2147584693 = 2147584764
103 + 2147584661 = 2147584764
107 + 2147584657 = 2147584764
113 + 2147584651 = 2147584764
167 + 2147584597 = 2147584764
211 + 2147584553 = 2147584764
263 + 2147584501 = 2147584764

Showing the first eight; more decompositions exist.
