Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618988, here are decompositions:

29 + 8618959 = 8618988
71 + 8618917 = 8618988
109 + 8618879 = 8618988
127 + 8618861 = 8618988
137 + 8618851 = 8618988
179 + 8618809 = 8618988
199 + 8618789 = 8618988
229 + 8618759 = 8618988

Showing the first eight; more decompositions exist.
