Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997388, here are decompositions:

5 + 4294997383 = 4294997388
107 + 4294997281 = 4294997388
127 + 4294997261 = 4294997388
131 + 4294997257 = 4294997388
167 + 4294997221 = 4294997388
191 + 4294997197 = 4294997388
197 + 4294997191 = 4294997388
229 + 4294997159 = 4294997388

Showing the first eight; more decompositions exist.
