Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961920, here are decompositions:

23 + 4294961897 = 4294961920
47 + 4294961873 = 4294961920
59 + 4294961861 = 4294961920
173 + 4294961747 = 4294961920
257 + 4294961663 = 4294961920
467 + 4294961453 = 4294961920
521 + 4294961399 = 4294961920
911 + 4294961009 = 4294961920

Showing the first eight; more decompositions exist.
