Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987228, here are decompositions:

71 + 4294987157 = 4294987228
167 + 4294987061 = 4294987228
239 + 4294986989 = 4294987228
269 + 4294986959 = 4294987228
317 + 4294986911 = 4294987228
461 + 4294986767 = 4294987228
491 + 4294986737 = 4294987228
599 + 4294986629 = 4294987228

Showing the first eight; more decompositions exist.
