Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961278, here are decompositions:

149 + 4294961129 = 4294961278
191 + 4294961087 = 4294961278
269 + 4294961009 = 4294961278
347 + 4294960931 = 4294961278
359 + 4294960919 = 4294961278
389 + 4294960889 = 4294961278
401 + 4294960877 = 4294961278
449 + 4294960829 = 4294961278

Showing the first eight; more decompositions exist.
