Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294998988, here are decompositions:

47 + 4294998941 = 4294998988
89 + 4294998899 = 4294998988
131 + 4294998857 = 4294998988
167 + 4294998821 = 4294998988
191 + 4294998797 = 4294998988
317 + 4294998671 = 4294998988
347 + 4294998641 = 4294998988
419 + 4294998569 = 4294998988

Showing the first eight; more decompositions exist.
