Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738838, here are decompositions:

29 + 8738809 = 8738838
37 + 8738801 = 8738838
71 + 8738767 = 8738838
79 + 8738759 = 8738838
109 + 8738729 = 8738838
127 + 8738711 = 8738838
131 + 8738707 = 8738838
167 + 8738671 = 8738838

Showing the first eight; more decompositions exist.
