Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997820, here are decompositions:

11 + 4294997809 = 4294997820
23 + 4294997797 = 4294997820
59 + 4294997761 = 4294997820
83 + 4294997737 = 4294997820
97 + 4294997723 = 4294997820
109 + 4294997711 = 4294997820
167 + 4294997653 = 4294997820
193 + 4294997627 = 4294997820

Showing the first eight; more decompositions exist.
