Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957278, here are decompositions:

11 + 4294957267 = 4294957278
71 + 4294957207 = 4294957278
89 + 4294957189 = 4294957278
179 + 4294957099 = 4294957278
197 + 4294957081 = 4294957278
211 + 4294957067 = 4294957278
389 + 4294956889 = 4294957278
397 + 4294956881 = 4294957278

Showing the first eight; more decompositions exist.
