Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991238, here are decompositions:

19 + 4294991219 = 4294991238
59 + 4294991179 = 4294991238
71 + 4294991167 = 4294991238
89 + 4294991149 = 4294991238
127 + 4294991111 = 4294991238
227 + 4294991011 = 4294991238
271 + 4294990967 = 4294991238
457 + 4294990781 = 4294991238

Showing the first eight; more decompositions exist.
