Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999868, here are decompositions:

127 + 4294999741 = 4294999868
151 + 4294999717 = 4294999868
331 + 4294999537 = 4294999868
541 + 4294999327 = 4294999868
571 + 4294999297 = 4294999868
661 + 4294999207 = 4294999868
751 + 4294999117 = 4294999868
1087 + 4294998781 = 4294999868

Showing the first eight; more decompositions exist.
