Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958920, here are decompositions:

17 + 4294958903 = 4294958920
59 + 4294958861 = 4294958920
179 + 4294958741 = 4294958920
191 + 4294958729 = 4294958920
269 + 4294958651 = 4294958920
293 + 4294958627 = 4294958920
383 + 4294958537 = 4294958920
683 + 4294958237 = 4294958920

Showing the first eight; more decompositions exist.
