Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994988, here are decompositions:

29 + 4294994959 = 4294994988
101 + 4294994887 = 4294994988
139 + 4294994849 = 4294994988
157 + 4294994831 = 4294994988
181 + 4294994807 = 4294994988
197 + 4294994791 = 4294994988
241 + 4294994747 = 4294994988
337 + 4294994651 = 4294994988

Showing the first eight; more decompositions exist.
