Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978990, here are decompositions:

17 + 4294978973 = 4294978990
41 + 4294978949 = 4294978990
179 + 4294978811 = 4294978990
191 + 4294978799 = 4294978990
233 + 4294978757 = 4294978990
257 + 4294978733 = 4294978990
311 + 4294978679 = 4294978990
431 + 4294978559 = 4294978990

Showing the first eight; more decompositions exist.
