Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997180, here are decompositions:

7 + 4294997173 = 4294997180
31 + 4294997149 = 4294997180
109 + 4294997071 = 4294997180
139 + 4294997041 = 4294997180
241 + 4294996939 = 4294997180
547 + 4294996633 = 4294997180
601 + 4294996579 = 4294997180
613 + 4294996567 = 4294997180

Showing the first eight; more decompositions exist.
