Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972866, here are decompositions:

5 + 4294972861 = 4294972866
7 + 4294972859 = 4294972866
43 + 4294972823 = 4294972866
59 + 4294972807 = 4294972866
73 + 4294972793 = 4294972866
139 + 4294972727 = 4294972866
257 + 4294972609 = 4294972866
263 + 4294972603 = 4294972866

Showing the first eight; more decompositions exist.
