Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738868, here are decompositions:

29 + 8738839 = 8738868
31 + 8738837 = 8738868
59 + 8738809 = 8738868
67 + 8738801 = 8738868
101 + 8738767 = 8738868
109 + 8738759 = 8738868
139 + 8738729 = 8738868
157 + 8738711 = 8738868

Showing the first eight; more decompositions exist.
