Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999840, here are decompositions:

23 + 4294999817 = 4294999840
71 + 4294999769 = 4294999840
107 + 4294999733 = 4294999840
113 + 4294999727 = 4294999840
281 + 4294999559 = 4294999840
293 + 4294999547 = 4294999840
419 + 4294999421 = 4294999840
431 + 4294999409 = 4294999840

Showing the first eight; more decompositions exist.
