Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972944, here are decompositions:

13 + 4294972931 = 4294972944
47 + 4294972897 = 4294972944
83 + 4294972861 = 4294972944
137 + 4294972807 = 4294972944
151 + 4294972793 = 4294972944
193 + 4294972751 = 4294972944
281 + 4294972663 = 4294972944
331 + 4294972613 = 4294972944

Showing the first eight; more decompositions exist.
