Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961388, here are decompositions:

71 + 4294961317 = 4294961388
101 + 4294961287 = 4294961388
191 + 4294961197 = 4294961388
251 + 4294961137 = 4294961388
269 + 4294961119 = 4294961388
317 + 4294961071 = 4294961388
379 + 4294961009 = 4294961388
409 + 4294960979 = 4294961388

Showing the first eight; more decompositions exist.
