Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961872, here are decompositions:

11 + 4294961861 = 4294961872
29 + 4294961843 = 4294961872
293 + 4294961579 = 4294961872
389 + 4294961483 = 4294961872
419 + 4294961453 = 4294961872
743 + 4294961129 = 4294961872
863 + 4294961009 = 4294961872
941 + 4294960931 = 4294961872

Showing the first eight; more decompositions exist.
