Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971280, here are decompositions:

11 + 4294971269 = 4294971280
53 + 4294971227 = 4294971280
59 + 4294971221 = 4294971280
71 + 4294971209 = 4294971280
179 + 4294971101 = 4294971280
401 + 4294970879 = 4294971280
419 + 4294970861 = 4294971280
461 + 4294970819 = 4294971280

Showing the first eight; more decompositions exist.
