Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294993428, here are decompositions:

7 + 4294993421 = 4294993428
29 + 4294993399 = 4294993428
31 + 4294993397 = 4294993428
79 + 4294993349 = 4294993428
101 + 4294993327 = 4294993428
137 + 4294993291 = 4294993428
139 + 4294993289 = 4294993428
227 + 4294993201 = 4294993428

Showing the first eight; more decompositions exist.
