Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991178, here are decompositions:

11 + 4294991167 = 4294991178
17 + 4294991161 = 4294991178
29 + 4294991149 = 4294991178
59 + 4294991119 = 4294991178
67 + 4294991111 = 4294991178
167 + 4294991011 = 4294991178
211 + 4294990967 = 4294991178
397 + 4294990781 = 4294991178

Showing the first eight; more decompositions exist.
