Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985988, here are decompositions:

151 + 4294985837 = 4294985988
179 + 4294985809 = 4294985988
191 + 4294985797 = 4294985988
331 + 4294985657 = 4294985988
457 + 4294985531 = 4294985988
521 + 4294985467 = 4294985988
677 + 4294985311 = 4294985988
701 + 4294985287 = 4294985988

Showing the first eight; more decompositions exist.
