Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294998890, here are decompositions:

67 + 4294998823 = 4294998890
103 + 4294998787 = 4294998890
109 + 4294998781 = 4294998890
181 + 4294998709 = 4294998890
199 + 4294998691 = 4294998890
223 + 4294998667 = 4294998890
229 + 4294998661 = 4294998890
337 + 4294998553 = 4294998890

Showing the first eight; more decompositions exist.
