Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294951878, here are decompositions:

29 + 4294951849 = 4294951878
59 + 4294951819 = 4294951878
67 + 4294951811 = 4294951878
89 + 4294951789 = 4294951878
101 + 4294951777 = 4294951878
109 + 4294951769 = 4294951878
127 + 4294951751 = 4294951878
131 + 4294951747 = 4294951878

Showing the first eight; more decompositions exist.
