Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999780, here are decompositions:

3 + 4294999777 = 4294999780
11 + 4294999769 = 4294999780
17 + 4294999763 = 4294999780
47 + 4294999733 = 4294999780
53 + 4294999727 = 4294999780
59 + 4294999721 = 4294999780
233 + 4294999547 = 4294999780
317 + 4294999463 = 4294999780

Showing the first eight; more decompositions exist.
