Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978920, here are decompositions:

47 + 4294978873 = 4294978920
53 + 4294978867 = 4294978920
109 + 4294978811 = 4294978920
139 + 4294978781 = 4294978920
163 + 4294978757 = 4294978920
191 + 4294978729 = 4294978920
241 + 4294978679 = 4294978920
293 + 4294978627 = 4294978920

Showing the first eight; more decompositions exist.
