Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988140, here are decompositions:

11 + 4294988129 = 4294988140
17 + 4294988123 = 4294988140
251 + 4294987889 = 4294988140
281 + 4294987859 = 4294988140
293 + 4294987847 = 4294988140
383 + 4294987757 = 4294988140
389 + 4294987751 = 4294988140
617 + 4294987523 = 4294988140

Showing the first eight; more decompositions exist.
