Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999890, here are decompositions:

73 + 4294999817 = 4294999890
113 + 4294999777 = 4294999890
127 + 4294999763 = 4294999890
149 + 4294999741 = 4294999890
157 + 4294999733 = 4294999890
163 + 4294999727 = 4294999890
173 + 4294999717 = 4294999890
191 + 4294999699 = 4294999890

Showing the first eight; more decompositions exist.
