Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294988900, here are decompositions:

127 + 4294988773 = 4294988900
193 + 4294988707 = 4294988900
211 + 4294988689 = 4294988900
337 + 4294988563 = 4294988900
487 + 4294988413 = 4294988900
523 + 4294988377 = 4294988900
547 + 4294988353 = 4294988900
673 + 4294988227 = 4294988900

Showing the first eight; more decompositions exist.
