Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738874, here are decompositions:

31 + 8738843 = 8738874
37 + 8738837 = 8738874
61 + 8738813 = 8738874
73 + 8738801 = 8738874
107 + 8738767 = 8738874
163 + 8738711 = 8738874
167 + 8738707 = 8738874
233 + 8738641 = 8738874

Showing the first eight; more decompositions exist.
