Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990180, here are decompositions:

101 + 4294990079 = 4294990180
113 + 4294990067 = 4294990180
191 + 4294989989 = 4294990180
293 + 4294989887 = 4294990180
431 + 4294989749 = 4294990180
461 + 4294989719 = 4294990180
743 + 4294989437 = 4294990180
809 + 4294989371 = 4294990180

Showing the first eight; more decompositions exist.
