Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985820, here are decompositions:

11 + 4294985809 = 4294985820
17 + 4294985803 = 4294985820
19 + 4294985801 = 4294985820
23 + 4294985797 = 4294985820
79 + 4294985741 = 4294985820
127 + 4294985693 = 4294985820
137 + 4294985683 = 4294985820
163 + 4294985657 = 4294985820

Showing the first eight; more decompositions exist.
