Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738258, here are decompositions:

19 + 8738239 = 8738258
31 + 8738227 = 8738258
97 + 8738161 = 8738258
157 + 8738101 = 8738258
211 + 8738047 = 8738258
337 + 8737921 = 8738258
409 + 8737849 = 8738258
457 + 8737801 = 8738258

Showing the first eight; more decompositions exist.
