Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993440, here are decompositions:

19 + 4294993421 = 4294993440
37 + 4294993403 = 4294993440
41 + 4294993399 = 4294993440
43 + 4294993397 = 4294993440
107 + 4294993333 = 4294993440
113 + 4294993327 = 4294993440
149 + 4294993291 = 4294993440
151 + 4294993289 = 4294993440

Showing the first eight; more decompositions exist.
